World Basketball League (WBL) was a minor professional basketball league in the United States and Canada that ran from 1988 to 1992. It was founded as the International Basketball Association in November 1987, before changing its name prior to the 1988 season. One of the major differences between it and other leagues was that it had a height restriction. Players over 6 ft 5 in (1.95 m) were not allowed to play; this restriction was raised to 6 ft 7 in (2.0 m) in 1991.

Basketball Hall-of-Famer and Boston Celtic great Bob Cousy (6'1" tall) was one of the league's founders. Norm Drucker, a 25-year veteran referee with the National Basketball Association and American Basketball Association, and a former supervisor of officials for the NBA, served as the WBL's supervisor of officiating. One of the league's founders, Michael Monus, was eventually convicted of having embezzled $10 million to finance the league, from a privately owned company he had founded, Phar-Mor. He was sentenced to nine (9) years in federal prison.

In addition to games against other teams in the league, games were also played against international teams. The league had several of its games broadcast on television. In Canada, the games were broadcast on the CanWest Global System. In the United States, the games were broadcast on SportsChannel America. Mike Rice was the primary analyst for the SportsChannel broadcasts.

After the league folded in 1992, the surviving Canadian-based teams formed the National Basketball League. This league played two seasons before it folded as well.
