Lorne John "Gump" Worsley (May 14, 1929 – January 26, 2007) was a Canadian professional ice hockey goaltender. Born and raised in Montreal, Quebec, 'Gump' was given his nickname because friends thought he looked like a comic-strip character Andy Gump.

He spent the first seven seasons of his hockey career in various minor leagues before joining the NHL in 1952 with the New York Rangers. He won the Calder Memorial Trophy for his play as a rookie for a team that finished in last place. He was demoted for the following season for trying to ask for a pay raise only to return to the NHL in 1954, where he would spend the next nine years; in ten seasons for New York, they reached the postseason four times. He was traded to the Montreal Canadiens in the summer of 1963. With Montreal, he would go 29–7 in the postseason that saw the Canadiens win the Stanley Cup four times (1965, 1966, 1968, 1969) while Worsley won the Vezina Trophy in 1966 and 1968 for his goaltending. He was traded to the Minnesota North Stars on February 27, 1970, and played regularly until 1974; on March 29, 1970, he became the sixth goaltender to win 300 games.

He was inducted into the Hockey Hall of Fame in 1980.

Worsley played his first four years as a professional in the minor leagues, most notably for the New York Rovers of the Eastern Hockey League (EHL), the St. Paul Saints of the United States Hockey League (USHL), and the Saskatoon Quakers of the Western Hockey League (WHL). Between 1950 and 1952 he was named to the First All-Star Team three times and led the league in goaltending.

In the fall of 1952 he was signed by the New York Rangers of the NHL. Although he played for a last-place team, he won the Calder Memorial Trophy as rookie of the year. However, after asking for a pay increase of $500 a year, he was sent back down to the minor leagues the following season. In 1953-54, playing for the Vancouver Canucks of the WHL, he won the league's most valuable player award.

In 1954-55, Worsley returned to the Rangers, replacing Johnny Bower. He toiled for the Rangers for the next nine seasons, generally playing well for a poor team. In the 1955–56 New York Rangers season opener against the Chicago Blackhawks, Worsley made 43 saves, setting a franchise record. In that season, he set a new league record for most shots allowed (2,574) and most saves (2,376), both of which remain NHL records.

In the summer of 1963, Worsley became involved in the establishment of a players' union, and the Rangers promptly traded him to the Montreal Canadiens. He spent much of the next two seasons in the American Hockey League with the Quebec Aces and was named to the AHL's First All-Star Team in 1964. Returning to the NHL, Worsley played his best years for the Canadiens as the team won the Stanley Cup in 1965, 1966, 1968 and 1969. His best season was 1968, when he won the Vezina Trophy, attained a goals-against average of 1.98 — the lowest in his career — and earned eleven straight wins in the playoffs. In 1969–70, however, he had a dispute with general manager Sam Pollock over being demoted to the minors, and head coach Claude Ruel's decision to favor Rogatien Vachon made Worsley quit in the middle of the season. Pollock suggested Worsley accept a two-week conditioning stint to work his way back to the Canadiens, but the veteran netminder refused. Worsley was suspended for not reporting to the Canadiens' Montreal Voyageurs farm team and told Pollock he intended to retire.

Later in the season, however, the Minnesota North Stars expressed interest in Worsley, and the Canadiens traded him for future considerations on February 27, 1970. He starred with Minnesota for most of the following five years; his best season with the team was 1972, when he came second in the league with a 2.12 goals-against average and was named to play in the 25th National Hockey League All-Star Game. He retired after the 1973–74 season at the age of 44. Worsley was the second goaltender to win 300 games and lose 300 games, after Harry Lumley.
