The 1998–99 NHL season was the 82nd regular season of the National Hockey League. Twenty-seven teams played 82 games each.

The Dallas Stars finished first in regular season play. They won the Stanley Cup Championship over the Buffalo Sabres with a disputed overtime goal by Brett Hull.

Goaltenders continued to rule the league; only two teams, the Toronto Maple Leafs and the New Jersey Devils, averaged more than three goals scored per game. In addition, no player reached the 50-goal plateau. A total of 160 shutouts were recorded for the second-straight regular season.
