The 1984 Stanley Cup Finals was the championship series of the National Hockey League's (NHL) 1983–84 season, and the culmination of the 1984 Stanley Cup playoffs. It was contested between the Edmonton Oilers and the defending champion New York Islanders. The upstart Oilers won the best-of-seven series, four games to one, to win their first Stanley Cup, becoming the third post-1967 expansion team and first former World Hockey Association team to win the Cup, and also the first team based west of Chicago to win the Cup since the WCHL's Victoria Cougars became the last non-NHL team to win it in .
