Kourtney Kardashian Age 2026: How Old Is Kourtney?

Last updated: November 8, 2026  ·  By Nathan Cole

Kourtney Kardashian is 47 years old in 2026. She was born Kourtney Mary Kardashian on April 18, 1979, in Los Angeles, California, and turned 47 on April 18, 2026. She is the eldest of the six Kardashian-Jenner siblings — older than Kim by about a year and a half, and older than Kylie by more than 18 years.

Her age is the frame for the whole story. She was 24 when her father, lawyer Robert Kardashian, died in 2003. She was 27 when she co-founded the DASH boutique, 28 when Keeping Up With the Kardashians premiered, 30 when her first child was born, 39 when she launched the wellness brand Poosh, 43 when she married Travis Barker, and 44 when their son Rocky was born. At 47 she runs a supplements business that Forbes projects past $200 million in 2026 sales, and she is still the lead of the family’s Hulu show.

The number itself causes confusion: stale pages and clickbait videos still call her 46. This article settles it with the birth date, the milestone-by-milestone age table, the sibling comparison, and the freshest reporting — including the November 5, 2026 episode of The Kardashians in which she laughed off split rumors on camera. Every date below is tied to a named source.

How Old Is Kourtney Kardashian?

Kourtney Kardashian is 47 years old. She was born on April 18, 1979, in Los Angeles, California, which makes her the eldest of the six Kardashian-Jenner children. She turned 47 on April 18, 2026 — a birthday that fell in the middle of filming for season 8 of The Kardashians on Hulu.

The arithmetic is simple, but the confusion around it is worth addressing head-on. Search results still surface pages that call her 46, and a wave of clickbait videos in late 2026 claimed she was getting divorced at 46 — a claim fact-checked as false in November 2026, with the fact-check itself noting she was 46 in 2025 and is 47 in 2026. The stale pages were written before her April birthday and never updated. The correct figure, as of November 2026, is 47.

Her age matters to the story because she has spent her whole adult life on television. The cameras started rolling when she was 28, and they have barely stopped since. That means there is a public record of Kourtney Kardashian at 28, 35, 40, 43, 45 and 47 — a timeline most celebrities never get, and the reason this article can put an exact age on nearly every turning point of her life.

Early Life: The Lawyer’s Daughter

Kourtney Mary Kardashian was born in Los Angeles on April 18, 1979, the first child of Robert Kardashian and Kris Jenner. Her father was a lawyer — the Robert Kardashian who defended O.J. Simpson in the 1995 trial — and her mother was building the family business instincts that would later make Kris Jenner the most famous “momager” in entertainment. Kourtney grew up in Los Angeles and attended Marymount High School, a Catholic girls’ school in the city.

She was the only one of the Kardashian sisters to finish college. After two years at Southern Methodist University in Texas, she transferred to the University of Arizona and graduated in 2002 with a bachelor’s degree in theatre arts and a minor in Spanish. She was 23. The degree is a small fact that says a lot: while her sisters were building careers in front of cameras, Kourtney was the one who went away, studied, and came back with a diploma.

She was 24 when her father died on September 30, 2003, of esophageal cancer. Robert Kardashian was 59. The loss shaped the family — Kris has spoken about it for years — and it put Kourtney, as the eldest child, in a particular position. The next year she and her mother opened Smooch, a high-end children’s boutique in Calabasas, which ran for six years before closing in 2009. She was 24 when it opened and 30 when it closed. The boutique was her first business, and it taught her the retail habits she would use at DASH, Poosh and Lemme.

Kourtney Kardashian’s Age at Every Milestone

The fastest way to understand a 47-year-old life is to see the ages attached to the events. Here is the full arc:

Two patterns stand out. First, the business milestones cluster in her late thirties and forties: Poosh at 39, Lemme at 43, the $200 million projection at 47. The reality star of 28 became the wellness entrepreneur of 47. Second, the family milestones span the whole table: a child at 30, another at 33, another at 35, and a fourth at 44 — a 14-year spread that means she has been raising a toddler and a teenager at the same time for most of the last decade.

Keeping Up With the Kardashians: Famous at 28

Keeping Up With the Kardashians premiered on E! on October 14, 2007. Kourtney was 28 years old, the eldest sibling, and the one the show cast as the dry, deadpan counterweight to her sisters. Kim was 26, Khloé 23, Rob 20, Kendall 11 and Kylie 10. The premise was the family itself — the Calabasas house, the DASH store, the arguments at the kitchen table — and Kourtney’s role in it was the skeptic who said what everyone else was thinking.

The show ran for 20 seasons and ended in 2021, when Kourtney was 42. Fourteen years of weekly television is a career by itself, and the money matched the run: our Kourtney Kardashian biography reports she earned a reported $4.5 million per season in the later E! years, followed by the family’s nine-figure Hulu deal. In February 2026, all 20 seasons of KUWTK returned to Hulu, which put the 28-year-old Kourtney back on screens next to the 47-year-old one.

What the show did for her age story is unusual. Most celebrities get older in private and show the public a curated version. Kourtney got older on camera, season by season, with the audience watching her go from a 28-year-old boutique owner to a 42-year-old mother of three. The Hulu show that followed — The Kardashians, running since 2022 — picked up at 43 and is still running at 47. There is almost no gap in the public record of her adult life.

Spin-Offs and DASH: The Business Years

Before Poosh and Lemme, there was DASH. Kourtney co-founded the boutique with Kim and Khloé in 2006, when she was 27, in Calabasas. A second store followed in Miami in 2009 — the move that became the spin-off Kourtney and Khloé Take Miami — and a New York location followed. The spin-offs stacked up through her thirties: Kourtney and Kim Take New York, Kourtney and Khloé Take the Hamptons in 2014, and Dash Dolls in 2015. Each one was, in effect, a television commercial for the stores, and each one kept the family on air between seasons of the main show.

DASH closed in 2018, when Kourtney was 39. The boutiques had run for twelve years — a real run for a celebrity retail brand — and their closure cleared the way for the businesses that define her forties. The timing is the point: she was 39 when the old business ended and 39 when the new one began. Poosh launched on March 5, 2019, weeks before her fortieth birthday, and it marked a shift from selling clothes to selling a way of living.

Scott Disick and Motherhood: Three Children Before 36

Kourtney’s relationship with Scott Disick ran from 2006 to 2015 — nine years, most of her late twenties and early thirties, played out on the show. Their three children arrived in that window: Mason Dash Disick, born December 14, 2009, when she was 30; Penelope Scotland Disick, born July 8, 2012, when she was 33; and Reign Aston Disick, born December 14, 2014, when she was 35. Mason and Reign share a birthday, December 14, five years apart.

She was 36 when the relationship ended in 2015. The split did not end the co-parenting: Disick remains a regular presence on The Kardashians, and the two have raised the children together for a decade since. In November 2026, the children are 16, 14 and 11 — Mason turns 17 on December 14, 2026, and Reign turns 12 the same day. Kourtney has now been a mother for nearly 17 years, which is more than a third of her life.

Poosh and Lemme: The Wellness Empire After 39

Poosh, launched in March 2019 when Kourtney was 39, is a lifestyle and wellness platform — part editorial site, part shop — built around the way she actually lives: clean eating, non-toxic products, and the routines she had been posting about for years. It was her first solo brand, and it worked because it was specific. She was not selling a generic celebrity lifestyle. She was selling Kourtney’s version of one, and her audience knew the difference.

Lemme, launched on September 12, 2022, when she was 43, is the bigger business. Co-founded with Simon Huck and Nir Liberboim, the supplements line started with three products and grew fast: Forbes reports more than $30 million in revenue in its first 16 months, $13 million in TikTok Shop sales in November 2025 alone, and a projection past $200 million in 2026 sales. New launches stacked up through 2026 — Purr probiotic lollipops, Lemme Colostrum unveiled with Kim, and the Lemme Play libido gummy, which got a full scene in The Kardashians season 7 premiere.

The brand has also drawn scrutiny. A proposed class-action lawsuit filed in July 2026 put Lemme’s “natural GLP-1” marketing under a microscope, and the case is a reminder that a supplements business carries regulatory risk a clothing boutique never did. At 47, Kourtney is running a company that faces the same questions any wellness brand faces — and answering them on a reality show that films her life.

Travis Barker: Married at 43, a Baby at 44

Kourtney began dating Blink-182 drummer Travis Barker in 2021, when she was 42. The two had been neighbors and friends in Calabasas for years before the relationship started, and the courtship played out in public: a Las Vegas practice ceremony in April 2022, a civil ceremony at the Santa Barbara courthouse on May 15, 2022, and the religious wedding in Portofino, Italy, on May 22, 2022. She was 43. Barker, born November 14, 1975, was 46 at the wedding — about three and a half years older than Kourtney. The marriage blended two families: his children Landon, Alabama and stepdaughter Atiana, and her three.

Their son, Rocky Thirteen Barker, was born on November 1, 2023. Kourtney was 44. A fourth child at 44, after three children in her thirties, made the pregnancy itself a storyline — the show covered the fertility journey, the emergency fetal surgery in September 2023, and the birth. Rocky turned 3 on November 1, 2026. Barker turned 50 on November 14, 2025, and turns 51 on November 14, 2026 — the age gap between the couple is about three and a half years.

Kourtney Kardashian in 2026: Rumors, a Premiere, and a Vampire Ball

The 2026 season of The Kardashians gave Kourtney her most public week in years. On the November 5, 2026 episode, she laughed off claims that she and Barker live apart and are splitting, calling the stories “fabricated.” Her publicist had flagged a magazine report making the claim, and Kourtney’s on-camera answer — “tell them to print it” — became the headline. Just Jared and CheatSheet both covered the moment within a day. The rumor had started, by her own account, with a “dumb TikTok.” She was 47, on her own show, shutting down a story about her own marriage.

Season 8 premiered on October 8, 2026, and it carried a second story from her year. In November 2025, Jennifer Lawrence had called Kourtney “more annoying than ever” during a Vanity Fair lie detector test with Robert Pattinson. Kourtney answered on the premiere, telling her friend Simon Huck she had initially wanted to confront the Oscar winner, and that Lawrence later contacted her privately. The exchange was light — a joke about a fight that never happened — but it showed how the show still works at 47: a real moment, filmed, aired, and argued about online within hours.

October brought a lighter headline. On October 10, 2026, Kourtney attended stepson Landon Barker’s “Vampire’s Ball”-themed 23rd birthday in a plunging ’90s Jonquil lace slip dress with fake blood on her chin, captioning the photos “bite me.” E! News covered the party, and the photos traveled. The same year, Barker’s documentary Travis Barker: Louder Than Fear arrived on Hulu in the United States and Disney+ elsewhere, with Kourtney in the story of his life. At 47 she is still the eldest sibling, still the one the cameras follow home, and still the one who answers the rumors herself.

Kourtney vs Her Siblings: The Family Age Table

Kourtney is the eldest of six, and the gaps are wide. Kim is a year and a half younger. Khloé is five years younger. Rob is almost eight years younger. Kendall is sixteen and a half years younger, and Kylie is eighteen years younger. The family spans nearly two decades of births, which is why Kourtney was already an adult with a college degree when Kylie was still in elementary school.

Kendall turned 31 on November 3, 2026 — five days before this article’s publication date — and Kris turned 71 on November 5, 2026. The table is current as of November 8, 2026. The ages explain the family dynamic the shows have filmed for nineteen years: Kourtney was the adult in the room from the first episode, and at 47 she still is.

Height, Net Worth, and the Rest of the Numbers

Kourtney Kardashian’s height of 5 feet 1 inch (155 cm) makes her the shortest of the Kardashian-Jenner siblings — a fact the family jokes about on the show. Some listings put her at 5 feet 0 inches (152 cm), and the gap is a rounding difference rather than a real dispute: she is listed at 5 feet 1 inch by the most-cited profiles, including our own biography, and at 5 feet flat by a handful of thinner pages. Either way, she is the smallest sibling by several inches.

Her net worth in 2026 is estimated at $60–70 million, anchored at $65 million — the figure both Parade, in March 2026, and Celebrity Net Worth land on. The money has three acts, matching the age table: the television years, which paid a reported $4.5 million per season in the later E! years plus the family’s nine-figure Hulu deal; Poosh, the wellness platform from 2019; and Lemme, the supplements line from 2022, which Forbes projects past $200 million in 2026 sales. She has never disclosed her finances publicly, so the $65 million figure is an estimate, built from dated, named reporting rather than a single source.

Life at 47: Homes, Health, and the Daily Routine

At 47, Kourtney Kardashian’s daily life looks very different from the 28-year-old who opened DASH in 2006 — and the difference is the point of the Poosh brand. She lives in Calabasas, the city the family made famous, in a home that doubles as the backdrop for much of the show’s domestic footage. The house is where the blended family gathers: her four children, Barker’s children, and the extended Kardashian-Jenner orbit that has always run through the eldest sister’s kitchen.

The wellness routine is the business and the lifestyle at once. Poosh, which she runs as founder and editor, publishes the routines she follows herself — the morning matcha, the non-toxic product swaps, the workouts, the food. It is a content model that only works if the founder lives it, and at 47 she does: the brand’s authority rests on the fact that the woman selling the supplements takes them, the woman selling the lifestyle lives it, and the audience has watched her do both for years. Lemme’s growth — past $30 million in its first 16 months, a projected $200 million-plus in 2026 — is the commercial proof that the model works.

Health is also the reason the age question follows her. A 47-year-old mother of four who had a baby at 44 draws a different kind of attention from a 28-year-old reality star, and Kourtney has used that attention deliberately. The fertility journey she and Barker documented on the show — the attempts, the treatments, the emergency fetal surgery in September 2023 — was unusually open for a celebrity pregnancy, and it made her a reference point for women having children later in life. The message was not that 44 is easy. It was that 44 is possible, and that the hard parts belong in the story.

The role of eldest sibling has grown with the age. At 28 she was the sister who rolled her eyes at the cameras. At 47 she is the one the younger siblings call, the one who hosts the family gatherings, and the one whose house the show returns to when it needs a scene that feels like home. Kim, at 46, runs a billion-dollar shapewear empire. Khloé, at 42, runs Good American. Kendall, at 31, is a working supermodel. Kylie, at 29, runs a cosmetics empire. Kourtney’s business is smaller than theirs by revenue, and she has never pretended otherwise. Her answer to that comparison has always been the same: she built the one that looks most like her life.

Social media is where the age arithmetic shows up most plainly. Her posts are tagged, dated and archived by fans, which is why the stale-age problem exists at all: a photo from January 2026 says 46 in its caption, and the caption never changes. The same archive is what makes the correction easy. The birth date is public, the birthday is public, and the math is public. A reader who wants the real number only has to check the date on the post.

What comes next is already in motion. Season 8 of The Kardashians is airing, Lemme is expanding into new product lines, and the July 2026 lawsuit over its marketing will work its way through the courts. Rocky is 3, Mason is about to turn 17, and the household is, as it has been for years, a mix of a toddler and teenagers. Kourtney Kardashian at 47 is not a former reality star. She is a working mother of four, running a growing company, on a show that has filmed her for nineteen years — and the next birthday, April 18, 2027, will make her 48.

The public image has shifted with the age, and the shift is visible in the coverage. The 28-year-old on the first season of KUWTK was written about as the sarcastic sister. The 47-year-old in the November 2026 headlines is written about as the founder, the mother of four, and the woman who answers rumors on her own show. The sarcasm is still there — “tell them to print it” is a Kourtney line through and through — but the context around it has changed. She is no longer the eldest sibling reacting to her family’s fame. She is a business owner whose company is projected to do more than $200 million in sales, a mother whose youngest is 3 and whose oldest is about to turn 17, and a television lead in her nineteenth year on air. The age is not a trivia answer. It is the measure of how long she has been doing this, and how much of it she built herself.

Why Some Pages Still Say She Is 46

Three things keep the wrong number alive. First, the calendar: Kourtney was 46 for the first three and a half months of 2026, from January 1 to April 17, and every page written in that window was correct when it was published. Pages that were never updated after her April 18 birthday still say 46, and search engines keep surfacing them.

Second, the clickbait economy. A wave of videos in late 2026 claimed a “46-year-old Kourtney Kardashian” was getting divorced for a fourth time. The claim was false — she has been married once, to Barker, and the November 5 episode addressed the rumor directly — but the videos used the stale age in their titles, and titles travel further than corrections. A fact-check published in November 2026 noted the point explicitly: she was 46 in 2025, when most of the clickbait started, and is 47 in 2026.

Third, the family itself invites the confusion. Kim is 46, and the two sisters are often photographed together, so a reader who sees “Kardashian, 46” and guesses wrong has a one-in-two chance of landing on the wrong sister. The fix is the birth date: April 18, 1979 for Kourtney, October 21, 1980 for Kim. Kourtney is 47. Kim is 46. The numbers will stay that way until April 18, 2027, when Kourtney turns 48.
