Peter Jon LoPresti (born May 23, 1954) is an American former professional 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 ice hockey for the University of Denver, and became the NHL's youngest regular goaltender that season. He was also a member of the United States men's national team in the 1976 Canada Cup as well as the Ice Hockey World Championships in 1976 and 1978.
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 1980–81 NHL season before retiring for good.
