Template:2021 Stanley Cup playoffs

In each round, teams compete in a best-of-seven series following a 2–2–1–1–1 format (scores in the bracket indicate the number of games won in each best-of-seven series). The team with home ice advantage plays at home for games one and two (and games five and seven, if necessary), and the other team is at home for games three and four (and game six, if necessary). The top four teams in each division make the playoffs.

In the First Round, the fourth seeded team in each division played against the division winner from their division. The other series matched the second and third place teams from the divisions. In the first two rounds, home ice advantage is awarded to the team with the better seed. Thereafter, it is awarded to the team that had the better regular season record. Teams advancing to the Stanley Cup Semifinals are re-seeded one through four based on regular season record.
