The Kardashian-Jenner Family Tree: How They're All Related

Few modern families have been documented as thoroughly, or discussed as widely, as the Kardashian-Jenners. Between two marriages, blended siblings, half-siblings, and a fast-growing generation of grandchildren, it's easy to lose track of exactly how everyone connects. Here's the family tree laid out plainly, from Robert Kardashian Sr. to the youngest grandchildren.

Where It Starts: Robert Kardashian and Kris

The family's foundation is the marriage of Robert Kardashian Sr., an attorney best known publicly for his role in the O.J. Simpson trial, and Kris Houghton (later Kris Jenner). Together they had four children:

• Kourtney Kardashian (b. 1979)
• Kim Kardashian (b. 1980)
• Khloé Kardashian (b. 1984)
• Rob Kardashian (b. 1987)

Robert and Kris divorced in 1991, and Robert Kardashian Sr. passed away in 2003.

The Second Marriage: Kris and Caitlyn Jenner

Kris remarried Olympic gold medalist Bruce Jenner (now Caitlyn Jenner) in 1991. Caitlyn already had four children from two previous marriages, Burt, Casey, Brandon, and Brody Jenner, before she and Kris had two daughters together:

• Kendall Jenner (b. 1995)
• Kylie Jenner (b. 1997)

This is the key point that trips people up: Kendall and Kylie are half-sisters to Kourtney, Kim, Khloé, and Rob, sharing their mother Kris but not their father. Burt, Casey, Brandon, and Brody Jenner, meanwhile, aren't blood-related to the Kardashian side at all. They became step-siblings through Caitlyn and Kris's marriage, and remain step-siblings today even though Kris and Caitlyn later divorced.

The Grandchildren's Generation

Kris Jenner's role as a grandmother now spans a large and growing group of children:

Parent	Children
Kourtney Kardashian	Mason, Penelope, Reign (with Scott Disick); Rocky (with Travis Barker)
Kim Kardashian	North, Saint, Chicago, Psalm (with Kanye West)
Khloé Kardashian	True, Tatum (with Tristan Thompson)
Rob Kardashian	Dream (with Blac Chyna)
Kylie Jenner	Stormi, Aire (with Travis Scott)

Kendall Jenner is the only one of Kris's six children without children of her own as of this writing. All of these cousins share Kris Jenner as their grandmother, but only Kourtney's, Kim's, Khloé's, and Rob's children also share Robert Kardashian Sr. as a great-grandparent; Kylie's children instead trace their other grandparent line back through Caitlyn Jenner.

Why the Family Tree Gets Confusing

A few specific things make this family harder to map than most:

• Two surnames from one household. Kardashian and Jenner children grew up together but carry different last names, which makes the "half" relationship easy to miss.
• Step-relationships without blood ties. Caitlyn's four older children are step-siblings to the Kardashians, not cousins or half-siblings. There's no shared parent at all.
• A very public timeline. Because the family's marriages, divorces, and births have played out on television and social media for close to two decades, it's easy to conflate "grew up in the same house" with "related by blood."

What This Family Tree Illustrates

Blended families like the Kardashian-Jenners are far more common than most family trees make room for. Traditional charts assume one parent, one set of children, and clean lines, but real families frequently include remarriage, step-siblings, half-siblings, and children from multiple relationships layered on top of each other. Mapping a family like this clearly means being explicit about which relationships are by blood and which are by marriage, exactly the kind of detail a good family tree tool should let you capture rather than flatten away.

Frequently Asked Questions

Are Kim Kardashian and Kylie Jenner full sisters?

No. They're half-sisters. They share the same mother, Kris Jenner, but have different fathers. Kim's father was Robert Kardashian Sr., while Kylie's father is Caitlyn Jenner.

How is Caitlyn Jenner related to the Kardashians?

Caitlyn Jenner isn't a blood relative of Kourtney, Kim, Khloé, or Rob Kardashian. She's their former stepfather (having transitioned publicly in 2015), through her marriage to their mother, Kris Jenner, and is the biological parent of their half-sisters, Kendall and Kylie.

Are Brody Jenner and Kim Kardashian related?

No. Brody Jenner is Caitlyn Jenner's son from an earlier marriage, making him a step-sibling to the Kardashians with no blood relationship at all.

Who are Kris Jenner's grandchildren?

Kris Jenner has grandchildren through five of her six children: Kourtney (Mason, Penelope, Reign, Rocky), Kim (North, Saint, Chicago, Psalm), Khloé (True, Tatum), Rob (Dream), and Kylie (Stormi, Aire). Kendall does not have children as of this writing.

Why do the Kardashian and Jenner children have different last names?

The last names reflect each parent's own family name. Kourtney, Kim, Khloé, and Rob take their father Robert Kardashian's surname, while Kendall and Kylie take their father Caitlyn Jenner's surname, a common pattern in blended families where children keep their biological father's name regardless of the household they grow up in.
