5 Shocking Ways The Kardashians And Jenners Are Connected: The Ultimate Family Tree Breakdown

The question of whether the Kardashians and Jenners are related is one of the most common searches in pop culture, and the answer is a definitive, yet complicated, "Yes." As of December 2025, the relationship is purely through the family's matriarch, Kris Jenner, who married two different men, creating one of the most famous blended families in modern history. While the Kardashian children (Kourtney, Kim, Khloé, and Rob) share a biological father, and the Jenner children (Kendall and Kylie) share a different biological father, all six siblings are connected through their mother, creating a complex web of half-siblings and step-relationships that define their global brand and reality television empire. The confusion stems from the fact that the two family names—Kardashian and Jenner—represent two distinct lineages that were merged by marriage. Understanding the full scope of their connection requires a deep dive into the marriages of Kris Jenner and the subsequent generations of children and grandchildren, all of whom contribute to the family's massive influence and financial power.

The Kardashian-Jenner Core Family: A Complete Roster

The Kardashian-Jenner empire is built on the foundation of six main siblings and their two parents, Kris Jenner and Caitlyn Jenner (formerly Bruce Jenner), alongside the late Robert Kardashian Sr. This list includes all of the primary figures that make up the central "Kardashian" and "Jenner" branches.

The Kardashian Branch (Children of Kris Jenner and Robert Kardashian Sr.)

• Kourtney Kardashian Barker: (Born 1979) The eldest sister. Her father is Robert Kardashian.
• Kim Kardashian: (Born 1980) Businesswoman and media personality. Her father is Robert Kardashian.
• Khloé Kardashian: (Born 1984) Television personality and entrepreneur. Her father is Robert Kardashian.
• Rob Kardashian: (Born 1987) The only son. His father is Robert Kardashian.

• Kendall Jenner: (Born 1995) Supermodel and media personality. Her father is Caitlyn Jenner.
• Kylie Jenner: (Born 1997) Businesswoman and youngest sibling. Her father is Caitlyn Jenner.

The Parents and Matriarch

• Kris Jenner (née Houghton): The family matriarch, mother to all six siblings. She was married to Robert Kardashian (1978–1991) and then to Caitlyn Jenner (1991–2015).
• Robert Kardashian Sr.: (1944–2003) Famous attorney, father to the four Kardashian children.
• Caitlyn Jenner (formerly Bruce Jenner): Olympic gold medalist, father to Kendall and Kylie Jenner, and step-parent to the four Kardashian children.

The Blended Family Tree: Half-Siblings and Step-Relationships Explained

The relationship between the Kardashians and Jenners is a classic example of a modern blended family, but on a massive, globally recognized scale. The key to understanding their connection lies in the two marriages of Kris Jenner.

1. The Kardashian Connection: Full-Blood Siblings

The first four children—Kourtney, Kim, Khloé, and Rob—are full-blood siblings. They share both their mother, Kris Jenner, and their late father, Robert Kardashian Sr. This group is the core of the "Kardashian" name and lineage. They are all connected by Armenian heritage through their father.

2. The Jenner Connection: Full-Blood Siblings

The two youngest children—Kendall and Kylie—are also full-blood siblings. They share both their mother, Kris Jenner, and their father, Caitlyn Jenner. This group carries the "Jenner" name.

3. The Half-Sibling Relationship: The Crucial Link

This is the most important part of the family dynamic and the direct answer to how the two groups are related. The four Kardashians (Kourtney, Kim, Khloé, Rob) and the two Jenners (Kendall, Kylie) are half-siblings. They all share the same biological mother, Kris Jenner, but have different biological fathers (Robert Kardashian and Caitlyn Jenner, respectively). This shared parent is the sole biological link that connects all six of the famous siblings.

4. The Step-Relationships: Caitlyn’s Extended Family

When Kris Jenner married Caitlyn Jenner (then Bruce Jenner) in 1991, the four Kardashian children gained a new step-parent. Caitlyn Jenner also has four older children from previous marriages: Burt, Cassandra, Brandon, and Brody Jenner. This means:

• Kourtney, Kim, Khloé, and Rob Kardashian are step-siblings to Burt, Cassandra, Brandon, and Brody Jenner.
• Kendall and Kylie Jenner are half-siblings to Burt, Cassandra, Brandon, and Brody Jenner (as they share Caitlyn as a father).

This intricate web of step- and half-siblings is what makes the Kardashian-Jenner family tree so "komplicated," as often referenced by the family itself.

The Next Generation and Current Family Dynamics

The family's story doesn't end with the six siblings; it continues to grow with a large number of grandchildren, often referred to as "The Next Generation." As of late 2025, Kris Jenner is the proud "Lovey" to over a dozen grandchildren, all of whom are cousins and represent the ultimate fusion of the Kardashian and Jenner names.

A Growing List of Kardashian-Jenner Grandchildren

All the grandchildren are first cousins to one another, solidifying the family's deep connection. The grandchildren include:

Kourtney Kardashian's Children (with Scott Disick and Travis Barker)

• Mason Dash Disick
• Penelope Scotland Disick
• Reign Aston Disick
• Rocky Thirteen Barker (with Travis Barker)

Kim Kardashian's Children (with Kanye West)

• North West
• Saint West
• Chicago West
• Psalm West

Khloé Kardashian's Children (with Tristan Thompson)

• True Thompson
• Tatum Thompson

Rob Kardashian's Child (with Blac Chyna)

• Dream Renée Kardashian

Kylie Jenner's Children (with Travis Scott)

The Evolving Family Dynamics

While the family is biologically and legally connected, the personal relationships have seen their share of ups and downs, particularly concerning Caitlyn Jenner. Recent reports have indicated a significant strain between Caitlyn and the Kardashian side of the family. Caitlyn has publicly stated that she has "lost all relationship" with her ex-wife, Kris Jenner, and her step-children, the Kardashians, though she remains close with her biological daughters, Kendall and Kylie Jenner. However, the core six siblings—Kourtney, Kim, Khloé, Rob, Kendall, and Kylie—continue to present a united front, often appearing together on their reality show, *The Kardashians*, and supporting each other's numerous business ventures, from SKIMS and Good American to Kylie Cosmetics. The blending of their lives, both personal and professional, is what has cemented their status as a single, powerful entity in the entertainment world. The Kardashian-Jenner relationship is a testament to the power of a shared maternal bond. They may carry different last names and have different biological fathers, but the six siblings are undeniably half-siblings, forever linked by their mother, Kris Jenner, and the massive, sprawling dynasty they have built together. The family's ability to navigate these complex relationships while maintaining a cohesive public image is the secret sauce behind their enduring relevance and topical authority in global media.
