Giannis Antetokounmpo’s oldest brother is Kostas Antetokounmpo, the eldest son of Charles and Veronica Antetokounmpo. Born in Athens, Greece, Kostas grew up in a tight-knit household that faced financial strain before the family gained stability in the United States. Unlike Giannis, who entered the NBA directly from high school, Kostas chose college, playing one season at the University of Dayton before declaring for the 2018 NBA draft. He was selected by the Philadelphia 76ers in the second round and has since balanced time in the G League and overseas while remaining a supportive figure in Giannis’s life. This profile clarifies their relationship using verified sources and context about family background.
Defining the Oldest Brother
Within the Antetokounmpo family, Kostas is the firstborn son, making him Giannis’s oldest brother by birth order. The family consists of five brothers—Kostas, Thanasis, Giannis, Alex, and Kyle—along with two sisters, Katerina and Angelina. Charles and Veronica Antetokounmpo raised the children in Athens before moving to the United States in the mid-2000s. Kostas’s role as the eldest carries responsibilities that often include mentoring younger siblings and serving as a stabilizing presence during transitions in immigration status, housing changes, and evolving careers.
Kostas Antetokounmpo: Background and Early Life
Kostas was born in Athens, Greece, shortly after his parents relocated from Nigeria. The family faced financial uncertainty and lived in a cramped apartment while Charles worked as a street vendor. Academic focus and basketball were intertwined from an early age, with Kostas attending local Greek schools before joining youth basketball programs. His early experiences in Greece shaped his work ethic and adaptability, traits that carried into his basketball development and later influenced how he supported Giannis during the family’s move to Milwaukee.
Childhood in Greece
Growing up in Athens, Kostas and his brothers played basketball in neighborhood courts and informal settings. Family unity was central, as Charles and Veronica emphasized education alongside athletics. The transition to the United States brought new challenges, including language barriers and cultural adjustment, but the family’s bond remained strong. Kostas’s grounding in Greek culture and family values contributed to his measured approach when compared to the high-profile paths of his brothers.
Move to the United States and Education
In the United States, Kostas attended high school in Milwaukee, where he balanced academics with basketball. Unlike Giannis, who skipped college to enter the 2013 NBA draft, Kostas elected to play college basketball at the University of Dayton. His decision reflected a desire to develop as a player and earn a degree before pursuing professional opportunities. After one season, he entered the 2018 NBA draft and was selected by the Philadelphia 76ers, later splitting time in the G League and overseas leagues.
Relationship with Giannis Antetokounmpo
Kostas and Giannis share a close but distinct relationship, shaped by age difference, life paths, and public visibility. While Giannis became an international star, Kostas has largely operated in Giannis’s shadow, navigating a more low-profile professional journey. Media coverage often contrasts their trajectories, yet both brothers maintain a supportive dynamic. Giannis has acknowledged Kostas’s role in grounding the family, especially during early years in the U.S., and Kostas has expressed pride in Giannis’s achievements without seeking the same spotlight.
Public Appearances and Statements
Kostas has attended NBA games and family events when scheduling permits, offering quiet support rather than media spectacle. In limited interviews, he has credited Giannis for the family’s positive narrative and has emphasized the importance of education and preparation. Giannis, in turn, has credited his parents and siblings for shared sacrifices, noting that the family’s progress relied on collective effort. These statements underscore a relationship rooted in mutual respect rather than rivalry.

Family Structure and Other Siblings
The Antetokounmpo family includes seven children, with Kostas as the eldest followed by Thanasis, Giannis, Alex, Kyle, Katerina, and Angelina. Each sibling has pursued basketball or related paths, but Kostas’s position as oldest shapes his informal role as a mentor and example.

The sisters, Katerina and Angelina, have largely remained out of the public eye, reflecting the family’s preference for privacy in personal matters.
