Evgeni Valentinovich Berzin (Russian: Евге́ний Валенти́нович Берзин; born 3 June 1970 in Vyborg, Russia) is a Russian former road cyclist.

Coming from track cycling, where he successfully represented the Soviet Union at World Championships, he moved to Italy in 1992 and turned professional with Mecair–Ballan in 1993. His second season in 1994 was to be his best, with victories at the Giro d'Italia and Liège–Bastogne–Liège. He finished second at the 1995 Giro d'Italia, but failed to live up to high expectations in the years after. A brief spell in the race leader's yellow jersey and a stage win at the 1996 Tour de France were his last big results. In 1997, he unsuccessfully attempted to break Chris Boardman's hour record. He retired from the sport in 2001.
