The 1920–21 Hamilton Tigers season was the first season of play for the new Hamilton Tigers team in the National Hockey League (NHL). The Tigers finished in last place in both halves of the season and did not qualify for the playoffs. The team previously had played in Quebec City, where they were known as the Quebec Bulldogs, but had been sold to Hamilton interests in 1920. Joe Malone led the team in scoring, with 28 goals in 20 games.
