The National Hockey League (NHL) Conference Finals are the Eastern Conference and Western Conference championship series of the NHL. The Conference Finals are best-of-seven series, and comprises the third round of the Stanley Cup playoffs. The two series are played in late May (early June in 1995 and 2013, due to labour disputes that delayed the start of the season). The winners of the Eastern and Western Conference Finals receive the Prince of Wales Trophy and Clarence S. Campbell Bowl, respectively, and advance to face each other in the final round.
