The 1998–99 St. Louis Blues season was the team's 32nd season in the National Hockey League (NHL). Despite the loss of Brett Hull during the preceding off-season, the Blues made the Stanley Cup playoffs for the 20th-straight season after finishing in second place with a record of 37–32–13.

Off-season

Realignment came, as the NHL went from four to six divisions. Carolina, Florida, Tampa Bay and Washington were grouped in the Eastern Conference's new Southeast Division and Calgary, Colorado, Edmonton and Vancouver moved into the new Northwest Division in the Western Conference.
