Her older brother, Rob Kardashian, was born on March 17, 1987, placing Kourtney ahead of him in birth order. Among her sisters, Kim was born in 1980, Khloé in 1984, and Kylie in 1997, confirming that Kourtney is older than Kim, Khloé, and Kylie but younger than her father, Robert Kardashian.

Age Ranking Within the Kardashian Family

Order by Birth Year

When sorted by birth year, the family sequence begins with Robert Kardashian in 1944, followed by Kourtney in 1979, then Kim in 1980, Khloé in 1984, and finally Kylie Jenner in 1997. This timeline clarifies that Kourtney is not the oldest member of the entire family but is the oldest among her generation of siblings.

Media portrayals sometimes emphasize Kourtney as a stabilizing, elder figure within the group dynamic. Her role as a mother and long-standing presence in the spotlight contribute to the impression that she is the eldest, even though her father precedes her in age.

Clarifying Misconceptions About Age

Father vs. Siblings Age Gap

Because Robert Kardashian passed away in 2003, he is less visible in current conversations, which may lead some to assume Kourtney is the oldest living Kardashian. In reality, she is the oldest among her siblings but not the oldest member of the entire family tree.

Generational Context

The significant age difference between Kourtney and her children reinforces her status as a senior figure in the family. However, when addressing the specific question of whether she is the oldest, the answer depends on whether the comparison includes parents and other relatives or focuses only on her siblings.
