They've been to the finals once, in 1998.
The Washington Capitals made it to the Stanley Cup Finals in 1998, and were swept in 4 games by the Detroit Red Wings.
Washington capitals
To date, they have never won the Stanley Cup.
Not yet.
Actually the US has not won any Stanley Cups as the trophy is not a national award given to national teams of any country. Many NHL teams based in American cities have won the championship, including this year by the Boston Bruins. For a list of US based teams that have won, simply Google "Stanley Cup Winners" and see those cities for yourself!
1998. The Detroit Red Wings swept the the Washington Capitals to win the 1998 Stanley Cup.
