The 1997–98 Washington Capitals season saw the team reach the Stanley Cup Finals for the first time in club history.
Peter Bondra's 52 goals led the team; veterans Dale Hunter, Joe Juneau, and Adam Oates returned to old form; and Olaf Kolzig had a solid .920 save percentage as the Caps got past the Boston Bruins, Ottawa Senators and Buffalo Sabres (the latter on a dramatic overtime win in Game 6 on a goal by Juneau) en route to the team's first Stanley Cup Finals appearance.
However, they were no match for the defending cup champs, the Detroit Red Wings, who won in a four-game sweep.
The Capitals had a very effective penalty kill during the regular season, allowing the fewest power-play goals (39) and finishing with the highest penalty-kill percentage (89.23%).
In the playoffs, the Capitals reached the Conference Finals for the first time since 1990, defeating the Buffalo Sabres in six games before reaching the Stanley Cup Finals where they lost to the Detroit Red Wings in four games.
