So, everyone knows the Kardashians. You've seen the memes, the TikToks of the 2026 Golden Globes, and the endless "get ready with me" videos. But if you actually try to map out the Kendall Jenner siblings situation, it gets messy fast. Like, genuinely confusing.
Most people think of Kendall as just the "older one" of the two Jenner girls who hang out with Kim, Kourtney, and Khloé. Honestly, that's barely half the story. Kendall actually has nine siblings. Yeah, nine. If you're counting the "core" group you see on The Kardashians, you're missing a huge chunk of the family tree that doesn't really do the whole reality TV thing.
The Sisters Everyone Knows (But Sorta Misunderstands)
We have to start with the obvious. Kendall and Kylie Jenner are the only two "full" siblings in the bunch, meaning they share both Kris and Caitlyn Jenner as parents. But even that relationship has its own weird vibe. Kendall has always been the one "doing her thing," as Caitlyn put it recently, while Kylie is more of an "open book" who sticks close to the family home base.
Then you've got the Kardashian sisters: Kourtney, Kim, and Khloé. Technically, these are Kendall’s half-sisters.
Khloé Kardashian has been super vocal about how much she hates that label. She’s gone on record—most recently on her Khloé in Wonder Land podcast—saying it’s "insulting" when people call them half-siblings. To her, they’re just sisters. Period. They grew up in the same house, shared the same snacks, and dealt with the same Kris Jenner "momager" energy.
- Kourtney Kardashian Barker (born 1979): The eldest. She and Kendall have a massive 16-year age gap.
- Kim Kardashian (born 1980): The middle-child-turned-mogul.
- Khloé Kardashian (born 1984): The one who basically acted like a second mom to Kendall and Kylie when they were babies.
It's funny because you see them on screen and they look like a unit, but the age gaps mean they were in completely different life stages. When Kendall was starting middle school, Kim was already... well, becoming Kim Kardashian.
The "Other" Jenner Siblings You Rarely See
This is where it gets tricky. Before Caitlyn (then Bruce) married Kris, there were two other marriages. That produced four more Kendall Jenner siblings who mostly stay out of the Calabasas circus.
First, there’s the marriage to Chrystie Scott. That gave us Burt Jenner and Cassandra "Casey" Marino. Burt is a big racing guy—follows in his dad's footsteps but with trucks and off-road stuff. Casey stays almost entirely out of the spotlight. She’s married, has kids, and lives a pretty "normal" life for someone whose sister is a supermodel.
Then came the marriage to Linda Thompson, which gave us the Malibu brothers: Brandon and Brody Jenner.
You probably remember Brody from The Hills or that brief window where he was actually on Keeping Up with the Kardashians. He’s the one who always seemed a bit salty about the family dynamic. He and Brandon were basically raised by their stepfather, David Foster. There's been a lot of talk over the years about how "estranged" they felt from Caitlyn once the Kardashian empire took off.
Why the Dynamic Feels "Off" Sometimes
If you've ever watched the show and thought, Wait, does Kendall even talk to her brothers?—you're not alone. It’s a common Reddit rabbit hole.
The reality is that the family is split into two distinct camps: the "Kardashian" side (which includes Kendall and Kylie) and the "Original Jenner" side. Kendall and Kylie didn’t grow up in the same house as Burt or Casey. They didn't even spend much time with Brandon and Brody until they were a bit older.
There’s some real history there. For instance, Kendall and Kylie didn't even RSVP to Brody’s wedding back in the day. That’s the kind of stuff that leaves a mark. While they all show up for the big Christmas Eve parties (the ones Khloé recently confirmed she pays for, by the way), the day-to-day bond isn't the same.
The Full Sibling Breakdown (Age Order)
- Burt Jenner (1978): The oldest of the bunch.
- Kourtney Kardashian (1979): The oldest on the Kris side.
- Casey (Jenner) Marino (1980): The low-key sister.
- Kim Kardashian (1980): Born just months after Casey.
- Brandon Jenner (1981): The musician/singer.
- Brody Jenner (1983): The TV star and DJ.
- Khloé Kardashian (1984): The protector.
- Rob Kardashian (1987): The only boy on the Kris side.
- Kendall Jenner (1995): The high-fashion model.
- Kylie Jenner (1997): The youngest of the whole crew.
The Rob Factor
We can't talk about Kendall Jenner siblings without mentioning Rob. He’s the only brother she actually grew up with. Rob has been a ghost in the media for years now, mostly focusing on raising his daughter, Dream.
Kendall and Rob’s relationship has always been a bit more private. While the sisters are busy filming every second of their lives, Rob opted out of the spotlight due to his struggles with mental health and privacy. But they’re still tight. You’ll catch glimpses of him at family dinners or in the background of a random Instagram story, usually just being a "normal" older brother.
Real Talk: The "Half-Sibling" Stigma
Is it weird to have so many half-siblings? Maybe to us. But for Kendall, this is just life. She's the bridge between two very different worlds.
On one hand, she’s part of the most famous female dynasty on the planet. On the other, she has brothers who would rather be in a garage or on a surfboard than at a Met Gala. That might be why Kendall always felt a bit like the "tomboy" or the "outlier" in the Kardashian family. She grew up watching her older brothers, and it influenced her style and her vibe more than people realize.

There’s also the niece and nephew situation. As of 2026, the Kardashian-Jenner grandkids list is getting ridiculous. Kendall is an aunt to over a dozen kids. From Kourtney’s new baby, Rocky, with Travis Barker, to Kylie’s kids Stormi and Aire, the family is expanding way faster than most people can track.
How to Keep Track (Actionable Tips)
If you're trying to keep the Kendall Jenner siblings straight for your next trivia night or just to understand the latest episode of The Kardashians, here’s the cheat sheet:
- Look at the Mom: If the mom is Kris, they’re the "TV Famous" ones (Kourtney, Kim, Khloé, Rob, Kylie).
- Look at the Dad: If the dad is Caitlyn, you’ve got the Jenner pack (Burt, Casey, Brandon, Brody, Kylie).
- The "Core Four": Kendall, Kylie, Kim, Khloé, and Kourtney are the ones who share the same branding and business orbit.
- The "Quiet Ones": Burt and Casey. They aren't looking for followers. Respect the hustle.
The biggest takeaway here is that "family" for Kendall Jenner isn't just what you see on a 45-minute Hulu episode. It’s a massive, complicated, multi-decade web of marriages, divorces, and blended households. It’s not perfect, and they don't all get along all the time, but it’s definitely never boring.
Next time you see Kendall on a runway, just remember she’s got a brother somewhere in the desert racing a truck who probably hasn't even seen her latest Vogue cover—and she’s totally fine with that.
