The 1998 Stanley Cup Finals was the championship series of the National Hockey League's (NHL) 1997–98 season, and the culmination of the 1998 Stanley Cup playoffs. It was contested by the Western Conference champion and defending Stanley Cup champion Detroit Red Wings and the Eastern Conference champion Washington Capitals. It was the 105th year of the Stanley Cup being contested. The series was the Capitals' first Stanley Cup Finals appearance in franchise history. The Red Wings swept the Capitals to repeat as Stanley Cup champions, capturing their ninth Stanley Cup in team history. This also marked the fourth consecutive Stanley Cup Finals to end in a sweep, and as of 2024 is the last Cup Final to end in a sweep.
Detroit coach Scotty Bowman won his eighth Stanley Cup in that capacity (having previously done so with the Montreal Canadiens in 1973, 1976, 1977, 1978, and 1979, the Pittsburgh Penguins in 1992, and the Wings the previous year), tying him with former Canadiens coach Toe Blake for the record of most Cups won by a coach (which he would break when he helped the Red Wings win the 2002 Cup).
