Peter Li Preti (born 1951 or 1952) was a city councillor in Toronto, Ontario, Canada, who represented one of the two York West wards from 1985 to 2006.
Li Preti was appointed to fill a vacancy on North York City Council in 1985 when former alderman Claudio Polsinelli ran for a seat in the provincial legislature.
Prior to the 1993 federal election, Li Preti had sought the Liberal Party nomination in the York Centre riding.
Besides Li Preti and his supporters, the appointment was criticized by several high profile Toronto Liberals including Joe Volpe, Dennis Mills, and John Nunziata.
Several incidents occurred during advanced polling on the weekend of November 4–5, 2006, leading to Li Preti and Perruzza accusing each other of dirty campaigning and the breaking of numerous elections.
