The 1980 Stanley Cup Finals was the championship series of the National Hockey League's (NHL) 1979–80 season, and the culmination of the 1980 Stanley Cup playoffs. It was contested by the New York Islanders in their first-ever Finals appearance and the Philadelphia Flyers, in their fourth Finals appearance, and first since 1976. The Islanders would win the best-of-seven series, four games to two, to win their first Stanley Cup championship and the third for a post-1967 expansion team after Philadelphia's Cup wins in 1974 and 1975.
