The 1994 Stanley Cup playoffs, the playoff tournament of the National Hockey League (NHL), began after the conclusion of the 1993–94 NHL season. The sixteen teams that qualified, eight from each conference, played best-of-seven game series for conference quarterfinals, semifinals and championships; and then the conference champions played a best-of-seven series for the Stanley Cup. The playoffs ended when the New York Rangers defeated the Vancouver Canucks in the seventh game of the 1994 Stanley Cup Finals. In total, an NHL record seven game sevens were played in this year's playoffs, two of which went to overtime.

The Stanley Cup playoffs is the annual elimination tournament to determine the winner of the Stanley Cup, and by default the league champion of the National Hockey League (NHL). The four-round, best-of-seven tournament is held after the NHL's regular season. Eight teams from each of the league's two conferences qualify for the playoffs based on regular season points totals. The final round is commonly known as the Stanley Cup Finals, which matches the two conference champions.
