The 1998–99 NBA season was the 31st season for the Phoenix Suns in the National Basketball Association. During the off-season, the Suns signed free agent Tom Gugliotta, acquired Luc Longley from the Chicago Bulls, acquired rookie forward Pat Garrity from the Dallas Mavericks, signed Chris Morris, and re-signed former Suns center Joe Kleine. Head coach Danny Ainge returned for his third season with the team. After a 15–18 start, the Suns won 12 of their final 17 games, and finished tied with the Sacramento Kings for third in the Pacific Division with a record of 27–23, in the shortened lockout season, which cut the regular season to just 50 games instead of the full 82 games. All home games were played in America West Arena.
