Flyers–Islanders rivalry

The Flyers–Islanders rivalry is a National Hockey League (NHL) rivalry between the Philadelphia Flyers and New York Islanders. Both teams compete in the Metropolitan Division of the Eastern Conference. The rivalry originates from the first playoff meeting between the two teams in 1975, and saw its peak during the late 1970s and early 1980s, as the two teams were perennial Stanley Cup contenders and met in the Stanley Cup playoffs three more times in the span of 13 years. After the 1980s, the rivalry saw a decline until a brief resurgence in 2020, when the two teams met for the fifth time in the playoffs. Both teams have competed in the same division together since the 1974–75 season. Along with the history behind the several playoff meetings between the two teams, the rivalry is also influenced by the proximity between the city of Philadelphia and the New York area, similar to the Flyers–Rangers and Devils–Flyers rivalries.
