Pete John Leswick (July 12, 1916 – June 20, 2005) was a Canadian ice hockey right winger. In the 1936–37 season, he played one game for the New York Americans, and scored one goal. In the 1944–45 season, he played two games for the Boston Bruins.
Born in Saskatoon, Saskatchewan, Leswick was noticed by the Rangers when he toiled for the senior Saskatoon Wesleys in his home town. He scored a goal in his only NHL game with the Blueshirts in 1936-37 and spent most of his rookie pro season with the AHL's New Haven Eagles. He then split the next seven seasons between the Pacific Coast Hockey League (PCHL) and the American Hockey Association (AHA). Leswick contributed to the Seattle Seahawks PCHL championship in 1938 then led all playoff scorers six years later when leading the New Westminster Royals to the title. In 1942 he was voted on to the AHA first all-star team after scoring 35 goals for the Fort Worth Rangers.
In October, 1944, the talented forward was signed by the Boston Bruins and played two NHL games for them that season. He then embarked on a productive AHL career with the Indianapolis Capitals and Cleveland Barons. Leswick helped the Barons win the Calder Cup in 1948 and scored at least 29 goals six straight years between 1945 and 1950. He was also placed on the AHL first all-star team four times and the second unit once.
