The 1990 Stanley Cup Finals was the championship series of the National Hockey League's (NHL) 1989–90 season, and the culmination of the 1990 Stanley Cup playoffs. It was contested by the Edmonton Oilers and the Boston Bruins; the Oilers won, four games to one. The series was a rematch of the 1988 Finals, albeit with the notable absence of Wayne Gretzky who was traded from Edmonton to the Los Angeles Kings during the 1988 off-season. For the Oilers, it was their fifth Cup win in seven years, and the team's only championship after trading Gretzky. This was the last of eight consecutive Finals contested by a team from Alberta and nine by a team from Western Canada.

The Boston Garden was an arena in Boston, Massachusetts. Designed by boxing promoter Tex Rickard, who also built the third iteration of New York's Madison Square Garden, it opened on November 17, 1928, as "Boston Madison Square Garden" and outlived its original namesake by 30 years. It was above North Station, a train station which was originally a hub for the Boston and Maine Railroad and is now a hub for MBTA Commuter Rail and Amtrak trains.
