Are all the Kardashians related? No. The core Kardashian family are blood relatives, but the wider group includes both blood relatives and people connected by marriage or partnership. Kris Jenner is the biological parent of Kourtney, Kim, Khloé, and Rob Kardashian. The Jenner sisters—Kylie and Kendall—are Kris’s daughters from her marriage to Caitlyn Jenner. The Kardashians by birth are Kourtney, Kim, Khloé, and Rob. Those married into the family, such as Kanye West, Travis Barker, and others, become relatives by marriage rather than by blood. This explainer clarifies how marriage, adoption, and half-sibling ties shape the broader Kardashian-Jenner network.
Defining the Kardashian Family
To determine whether all the kardashians are related, it helps to distinguish between family by birth and family by marriage. In everyday usage, the term “Kardashians” often refers to both the blood relatives within the Kardashian household and the high-profile figures who joined through marriage to the women in the family. This distinction is important when asking whether every person with the surname Kardashian or Jenner is directly related by blood. Below is a verified summary of biological relationships within the group.
Verified Biological Relationships (Blood Ties)

|---|---|---|
| Kris Jenner (née Houghton) | Biological mother of Kourtney, Kim, Khloé, and Rob Kardashian | Public records, biographies |
| Caitlyn Jenner (née Bruce) | Biological father of Kourtney, Kim, Khloé, and Rob; married Kris, then married others | Public statements, media reports |
| Kylie Jenner | Biological daughter of Kris Jenner and Caitlyn Jenner (step-daughter of Caitlyn post-transition) | Public birth records, family statements |

Family by Marriage and Partnership
Many high-profile figures associated with the name “Kardashian” are not biologically related to the core siblings. They become part of the extended circle through marriage, long-term partnership, or close friendship that is publicly presented as family. When people ask whether all kardashians are related, the answer often shifts depending on whether marriage and chosen family are included in the definition.
Key Examples of Relatives by Marriage or Partnership
- Kanye West — married to Kim Kardashian (2014–2021), father to her children; related by marriage and parenthood.
- Travis Barker — married to Kourtney Kardashian (2022 onward), stepfather to her children.
- Kris Humphries — was married to Kim Kardashian (2011–2013), no children together; related by a short-term marriage.
- Blac Chyna — was in a long-term relationship with Rob Kardashian and had a child with him; not married, but publicly presented as part of the family circle.
- Scott Disick — long-term partner of Kourtney Kardashian; father to her three children; stepfather by role, not by legal adoption.
- Khloé’s and Lamar Odom — married (2009–2016); related by marriage and shared parenthood of a child from a previous relationship who was legally adopted by Lamar.
- Austin Damon — Kendall Jenner’s former partner; not publicly treated as a family member in the same way as partners integrated into parenting or household life.
Kardashian-Jenner Network: Relationship Map Overview
Visualizing the kardashians family tree helps show which members share direct blood ties and which are linked through marriage or long-term partnership. The core blood group is the Kardashian siblings; Jenner siblings are their full siblings on their mother’s side. The network expands when partners and adoptive relationships are considered, but it does not mean that every person with a Kardashian-associated surname is directly related by blood.
Simplified Structure
- Kris Jenner and Caitlyn Jenner are the parents of the core siblings: Kourtney, Kim, Khloé, and Rob Kardashian.
- Kylie and Kendall Jenner are sisters to the core siblings, sharing both parents (Jenner-Kardashian lineage).
- Brandon Jenner and Burt Jenner are half-siblings to the core group, sharing Kris Jenner as a mother but different fathers.
- Partners such as Kanye West, Travis Barker, and Scott Disick are linked by marriage or long-term relationship rather than by blood.
Adoption and Legal Relationships
Adoption and legal guardianship add complexity to whether all the kardashians are related by blood. Lamar Odom legally adopted Kourtney and Kim’s nephew, the son of Kourtney and Scott Disick, which created a legal family bond with the Kardashian-Jenner household. Similarly, Khloé’s marriage to Lamar Oland tied her to Lamar’s son from a previous relationship, who was adopted by Lamar. These legal ties do not create blood relations but do integrate individuals into the broader family structure in meaningful ways.
Extended Connections and Public Perception
The public often treats close family friends and long-term partners as de facto family members, especially when they appear regularly on shared shows or events. In that broader social sense, many people may colloquially refer to associates as “Kardashians,” even when no blood or legal relationship exists. However, answering the question are all kardashians related requires focusing on verifiable ties—birth, adoption, and legal marriage—rather than social closeness or media portrayal.
Key Takeaways
The short answer to whether all the kardashians are related is no. The Kardashian siblings share both parents and are fully related to one another. Kylie and Kendall Jenner share the same parents and are full sisters to the Kardashian siblings. Half-siblings such as Brandon Jenner and Burt Jenner also share Kris Jenner as a biological parent. Many high-profile figures associated with the name are linked by marriage or long-term partnership rather than blood. Understanding these distinctions clarifies the structure of the Kardashian-Jenner network and corrects the common assumption that everyone with the Kardashian surname or public connection is directly related by birth.
