The 1975 Stanley Cup Final championship series was played by the Buffalo Sabres, making their first Finals appearance and the defending champion Philadelphia Flyers. The Flyers would win the best-of-seven series four games to two. This was the first Final to have two non-"Original Six" teams since the 1967 expansion. As of 2009, the 1975 Flyers are the last Stanley Cup championship team to be comprised solely of Canadian-born players.
Buffalo defeated the Chicago Black Hawks 4–1 and the Montreal Canadiens 4–2 to advance to the final. Philadelphia defeated the Toronto Maple Leafs 4–0 and the New York Islanders 4–3 to make it to the final.
Bernie Parent led the Flyers, allowing only 12 goals in the six games, capped with a shutout. He became the first player to win the Conn Smythe Trophy for two consecutive years. Since then, only Mario Lemieux has managed to duplicate this feat.
This championship is especially noted because it is the last repeat major professional championship for the city of Philadelphia.
