Fausto Gresini (born 23 January 1961) is an Italian former Grand Prix motorcycle road racing World Champion. He is currently team manager for the Gresini Honda MotoGP team.
Gresini was born at Imola. He began racing in 1978 at the age of 17 on a Minarelli 50 in Italy, and in 1983 he joined the Grand Prix circuit with the MBA team.
During his riding career, Gresini won two world championship titles in the 125cc class in 1985 and 1987. He was vice-champion in the 125cc class in 1986 aboard a Garelli and in 1991 and 1992 with Honda. He accumulated 21 victories and raced in 132 Grand Prix with 15 second places and 11 third places. He is tied with Ángel Nieto for the record of 11 consecutive victories in the 125 class, accomplished across 1986 and 1987.
