Peter Jon LoPresti (born May 23, 1954 in Eveleth, Minnesota) is a retired American ice hockey goaltender. He is the son of former National Hockey League (NHL) goaltender Sam Lopresti.
LoPresti started his NHL career with the Minnesota North Stars in 1974 after playing college hockey for the University of Denver, and became the NHL's youngest regular goalie that season. He was also a member of Team USA in the 1976 Canada Cup as well as the 1976 and 1978 Ice Hockey World Championship tournaments.
LoPresti lost his job as the North Stars starting goaltender in 1978–79 to Gilles Meloche and retired for the first time after failing to make the Edmonton Oilers roster the following season.
He would later briefly return to the Oilers for the 1981 season before retiring for good.
