Historical NBA franchises
Every BAA, NBA and ABA franchise that no longer exists, split by league.
ABA-only franchises
American Basketball Association franchises (1968-76) whose lineages did not merge into the NBA. The 1976 merger absorbed only the Pacers, Nets, Spurs, and Nuggets; everything below either folded, was bought out, or operated entirely outside the merger.
BAA / NBA defunct franchises
Basketball Association of America (1947-49) and early NBA franchises that folded, mostly during the league's first decade of consolidation.
About this page
Franchises that played at least one season in the Basketball Association of America (1947-49), National Basketball Association (1949+) or American Basketball Association (1968-76) but no longer exist as independent clubs. Includes the 8 ABA-only franchises whose lineages did not survive the 1976 NBA-ABA merger, the BAA charter members that folded before the 1949 merger, and one-season early NBA clubs.
