The Western Division of the ABA, or ABA Western Division, was one of the two groups in which the teams of the American Basketball Association were divided, based on their geographical location. The other group was called the Eastern Division (ABA), or ABA Eastern Division.
The first four teams in each division entered the ABA Playoffs. The divisions were maintained until the 1974–75 season, since in the last season the 9 surviving teams were regrouped in a single division.[1]
