Arthur Géa (born 2 January 2005) is a rising French professional tennis player from Velleron, Vaucluse, who achieved a career-high ATP singles ranking of No. 82 in August 2026. As a junior, he showed early promise by reaching the boys' doubles final at Wimbledon 2023 and the singles semifinals at the 2023 US Open, where he lost to American Learner Tien. After turning pro, he won multiple ITF titles in late 2023, made his ATP Tour debut in Marseille in February 2025, and received a wildcard for his Grand Slam doubles debut at the French Open that year. His major breakthrough came in 2026 when he claimed his first Challenger title in Nouméa, then made his Grand Slam singles debut at the Australian Open—defeating 17th seed Jiří Lehečka before falling to Stan Wawrinka in a five-set thriller. That same year, he reached his first ATP quarterfinal at the Open Occitanie and captured his maiden ATP Tour title at the Los Cabos Open, cementing his rise into the world's top 100. With rapid progression and a strong baseline game, Géa has quickly established himself as one of the most exciting young talents in French tennis.
