When you hear the name Kylie Jenner, you probably think of a beauty empire and reality TV royalty. But behind the billion-dollar brand is a family story that’s as captivating as any on-screen drama, centered around her large and blended family.

It’s a common question: just how many siblings does Kylie Jenner have? The answer is nine. She has one full sister and eight half-siblings, making for a truly complex and fascinating family tree. Let’s dive into the world of the Kylie Jenner siblings.

Kendall Jenner: Her Sister and Best Friend

First up is Kendall Jenner, Kylie’s only full sibling. Sharing parents Kris and Caitlyn Jenner, these two grew up in the spotlight together, creating a bond that’s visibly unbreakable. They aren’t just sisters; they’re best friends and partners in crime.

While Kylie was building her cosmetics empire, Kendall took the fashion world by storm, becoming one of the highest-paid supermodels on the planet. Even with their own demanding careers, they remain each other’s biggest cheerleaders, a constant presence in each other’s lives on and off camera.

The Famous Kardashian Sisters: Kourtney, Kim, and Khloé

On her mom’s side, Kylie has three of the most famous older half-sisters in the world: Kourtney, Kim, and Khloé Kardashian. They are the daughters of Kris Jenner and her first husband, the late Robert Kardashian.

Kourtney, the eldest, has made her mark with the wellness brand Poosh. Kim, a true global icon, transformed her fame into a multi-faceted empire of fashion and beauty. Khloé has found success as a TV host and founder of the inclusive clothing line Good American.

For Kylie, these sisters have been more than just family; they’ve been mentors and role models. Their dynamic, full of support and classic sisterly moments, has been a cornerstone of their family’s appeal.

Rob Kardashian: Her Only Half-Brother on the Kardashian Side

So, what about a brother? Rob Kardashian is Kylie’s older half-brother, the only son from Kris Jenner’s first marriage. He was a familiar face in the early days of their reality show but has since stepped back to lead a more private life.

Though he avoids the spotlight, Rob is still a cherished part of the family. He’s an entrepreneur with his sock line, Arthur George, and a dedicated father to his daughter, Dream, keeping his focus on family away from the public glare.

The Jenner Brothers: Burt, Brandon, and Brody

The Jenner family tree gets even more interesting on her father’s side. From Caitlyn Jenner’s previous marriages, Kylie has four more half-siblings, including the well-known Jenner brothers.

Burt Jenner, the oldest, is a businessman and professional racer who prefers a life away from the Hollywood scene. Brandon Jenner is a musician who has shared his talents on the family show, while Brody Jenner became a star in his own right on the reality series The Hills.

The relationship with the Jenner brothers has always been a bit more complicated and distant. They are part of the extended family, but their lives have largely unfolded separately from the core Kardashian-Jenner circle.

Cassandra Marino: The Most Private Sibling

The most private of all the Kylie Jenner siblings is her oldest half-sister, Cassandra Marino (née Jenner). She is from Caitlyn’s first marriage and has made a conscious choice to live her life completely out of the public eye.

Because she values her privacy, little is known about her connection with Kylie, but she holds her place as the eldest in the sprawling Jenner family tree.

A Modern Family Legacy

In the end, the story of the Kylie Jenner siblings is more than just a list of names. It’s a modern saga of a blended family that has built an empire, navigated immense fame, and redefined celebrity for a new generation.

From her inseparable bond with Kendall to the more complex ties with her other half-siblings, Kylie’s family is a diverse group of individuals who have each found their own way to shine. Their collective journey is a unique chapter in pop culture history.
