Robby Ginepri (born October 7, 1982) is an American tennis player who turned professional in 2001.

Ginepri had a breakout year in 2005. In August, he reached the semifinals of an ATP Masters Series tournament for the first time in his career, in Cincinnati, Ohio. He beat 2005 French Open runner-up Mariano Puerta in the first round, David Ferrer in the second round, 1998 French Open champion Carlos Moyà in the third round, and two-time Grand Slam singles titlist Marat Safin in the quarterfinals. He then lost to World No. 1 Roger Federer in the semifinals 4–6, 7–5, 6–4.

His summer hardcourt record was 14-3 when he arrived two weeks later at the U.S. Open as an unseeded player. After winning his first two matches in straight sets, Ginepri put together a string of five set wins, defeating Tommy Haas in the third round, Richard Gasquet in the fourth round, and Guillermo Coria in the quarterfinals. He then lost to Andre Agassi in the semifinals 6–4, 5–7, 6–3, 4–6, 6–3. Ginepri was the first player in the open era to play four consecutive five-set matches at the U.S. Open.
