The 1998 WNBA season was the Women's National Basketball Association's second season. The 1998 season saw two expansion teams join the league, the Detroit Shock and Washington Mystics. The expansion teams allowed the defending champions Houston Comets to move to the Western Conference. The regular season was extended from 28 games to 30 games. The season ended with the Comets winning their second WNBA championship. During the season, Kelly Boucher became the first Canadian to play in the league, suiting up for the Charlotte Sting.
