Giannis Antetokounmpo's Real Name: Giannis Sina Ugo Antetokounmpo

Quick answer: The NBA star known as the "Greek Freak" has the full name Giannis Sina Ugo Antetokounmpo, according to Olympedia and BlackPast. He was born December 6, 1994, in Athens, Greece, to Nigerian parents. Britannica gives his original name as Giannis Adetokunbo, the first spelling of the family surname, which was changed to Antetokounmpo around 2013 (Olympedia; Britannica).

Real name and early life

Britannica says Giannis Adetokunbo was born in Athens to Nigerian immigrants who had no legal status in Greece. Greece did not grant birthright citizenship, so he and three of his four brothers were considered stateless. The family faced money problems, xenophobia, and the fear of deportation. To help out, he sometimes sold items such as sunglasses and watches on the streets of Athens. BlackPast names his parents as Charles and Veronica.

He started playing basketball at about 13, when a local coach spotted him and his brothers. Thanasis, Kostas, and Alex also went on to play professionally. At about 16 he joined Filathlitikos, a professional club in Greece. Britannica says that in 2013, around the time the Bucks picked him, he gained Greek citizenship, which let him travel to the United States, and the family changed its surname to Antetokounmpo. The Library of Congress records his birthplace as Sepolia, a neighborhood of Athens.

Career highlights

The Milwaukee Bucks drafted him 15th overall in 2013. After winning Most Improved Player in 2016–17, he became the league's most dominant forward. He was named MVP in 2019 and 2020 and Defensive Player of the Year in 2020. Britannica notes he was only the third player, after Michael Jordan and Hakeem Olajuwon, to win both honors in the same season.

In the 2021 NBA Finals, the Bucks lost the first two games to the Phoenix Suns before winning four straight. Antetokounmpo scored 50 points in the deciding Game 6 and was named Finals MVP. It was Milwaukee's first title since 1971. Injuries and first-round exits followed from 2023 through 2025. In June 2026, the Bucks agreed to trade him to the Miami Heat, and the AP reported the deal was completed in July.

He has also starred for Greece and carried its flag at the opening ceremony of the 2024 Paris Olympics. In 2024 he married his longtime partner, Mariah Riddlesprigger. Britannica says the couple has four children.
