in the 2013 Eastern Conference Quarterfinals, with the Penguins coming out on top in six games. Both teams met in the 2019 Eastern Conference First Round and the 2021 East Division First Round, where the Penguins were favored both times, the former despite being the lower seed, but the Islanders surprisingly swept the series in 2019 and defeated them in six games in 2021, marking the first time the Islanders clinched a playoff series at Nassau Coliseum since 1993 and the last time the Islanders have won a playoff series in the venue, as they moved to UBS Arena in the 2021-22 season. As of the end of the 2021–22 season, Pittsburgh leads the regular season series 130–103–22–12 while New York leads the playoff record 21–14. New York Islanders vs. Washington Capitals The rivalry takes place in the Metropolitan Division.

They have met 11 times in the Stanley Cup playoffs, with the Flyers winning 6 times, and have been division rivals since the season.

Games between the two teams at Madison Square Garden and Wells Fargo Center are often very intense, hard-hitting affairs, as each home crowd does its best to create an unfriendly, sometimes volatile atmosphere for any visiting-team fans. New York Rangers vs. Pittsburgh Penguins Both franchises have been part of the same division on four different occasions: with the Patrick Division from 1981 to 1993, from 1998 to 2013 as part of the Atlantic Division, since 2013 as part of the Metropolitan Division, and in the 2020–21 season as part of the East Division. The Penguins and Rangers met in eight playoff series, with the Penguins winning five of them. Between 1989 and 1996, the two teams met thrice in the playoffs. The most memorable of
