Due to the league using an intra-divisional schedule during the regular season, none of the participants in the Stanley Cup semifinals played each other during this year's regular season. The last time this occurred was in 1924 when the Stanley Cup was contested by the champions of the NHL, PCHA and WCHL.

(1) Vegas Golden Knights vs. (4) Montreal Canadiens

This was the first playoff meeting between these two teams. This was Vegas' second consecutive semifinals/conference finals appearance and third within their four seasons of play.

They were also the first Canadian team since the Vancouver Canucks in 2011 to reach the Finals. This was the first Finals since 2009 to feature two teams in the same time zone. These teams did not play each other during this year's regular season.

Skaters

These are the top ten skaters based on points, following the conclusion of the playoffs.^[101]

Goaltenders

This is a combined table of the top five goaltenders based on goals against average and the top five goaltenders based on save percentage, with at least 420 minutes played. The table is sorted by GAA, and the criteria for inclusion are bolded.^[102]

In Canada, for the seventh postseason under Rogers Media's current 12-year contract, coverage was broadcast by Sportsnet and CBC under the Hockey Night in Canada brand, and streamed on Sportsnet Now, CBCSports.ca (for games televised by CBC), or the subscription service Rogers NHL Live.

For this season, lead play-by-play voice Jim Hughson did not call any of Sportsnet's playoff games, having opted to work only nationally televised Vancouver Canucks home games during the regular season.^[103] Consequently, Chris Cuthbert joined lead colour commentator Craig Simpson on Sportsnet's lead broadcast team, calling the Canadiens–Maple Leafs series on-site for the First Round,^[104] the Jets–Canadiens series in the Second Round,^[105] the Golden Knights–Canadiens series in the semifinals,^[106] and the entire 2021 Stanley Cup Finals.^[107] Harnarayan Singh and Louie DeBrusk served as the secondary team, doing a similar role for the Oilers–Jets series.^[104] John Bartlett and Garry Galley served as the tertiary team, calling a select number of games from the West, Central, and East Division series inside the Sportsnet studios on CBC, while those broadcast on Sportsnet were simulcasts of NBC Sports' feeds.^[104][105]

This marked the final postseason under NBC Sports' 10-year contract for American television rights to the NHL. All national coverage of games were aired on either NBCSN, the NBC broadcast network, NHL Network, USA Network, or CNBC.^[108][109] During the First Round, excluding games exclusively broadcast on NBC, the regional rights holders of each participating U.S. team produced local telecasts of their respective games.

After NBC's lead play-by-play voice Mike "Doc" Emrick retired at the end of the previous season, NBC split top play-by-play duties between Kenny Albert and John Forslund during the regular season. For the playoffs, Albert, Eddie Olczyk, and Brian Boucher served as the lead broadcast team^[110] while Forslund, Joe Micheletti, and Pierre McGuire served as the secondary team.^[111] Brendan Burke and A. J. Mleczko primarily served as the tertiary team.^[110] Rounding out NBC's broadcast crew were play-by-play voices Alex Faust, Ken Daniels, and John Walton, and analysts Keith Jones, Dominic Moore, and Jody Shelley. Most first-round games were called remotely, with a few others called on-site. For the Second Round, all games were called on-site except the Jets–Canadiens series.^[112] All games were called on-site starting with the semifinals. Peacock, NBC's streaming service, streamed all remaining games of the Stanley Cup playoffs starting on June 14.^[113]

As it had been done throughout the regular season due to COVID-19 protocols, the home broadcaster provided a neutral "world feed" to the other media partners for at the first two rounds: the home team's regional rightsholder during most first-round games in the U.S., NBC for the rest of the U.S. games, and Sportsnet for all games played in Canada.^[114]

Amazon Web Services debuted advanced shot and save analytics for the playoffs, taking data from the player and puck tracking technology that was first implemented at the start of the regular season.^[115] NBC used a redesigned score bug to display these new statistics.^[114]
