The National Professional Soccer League (NPSL) was a North American professional soccer league that existed for only the 1967 season before merging with the United Soccer Association (USA) to form the North American Soccer League.
 It had ten charter members, nine from the United States and one from Canada.
 To encourage attacking play, the NPSL introduced a new standings points system that was later used by the NASL – 6 points for a win, 3 for a draw, 0 for a loss and 1 bonus point for each of the first three goals scored.
 The circuit's commissioner was Ken Macker, an American publisher of three Philippines-based newspapers.
 The name National Professional Soccer League was revived in 1990 and used by a United States professional indoor soccer league.

Overview of the 1990 American Professional Soccer League season.
 Although the Western Soccer League and the American Soccer League merged to form the American Professional Soccer League in 1990, the two leagues remained essentially independent leagues, linked by name alone.
 During this season, they ran separate regular season schedules with two different points systems.
 They each had their own playoff formats, had separate league MVPs and had their own All League teams.
 The first game between the two leagues came in September when the Maryland Bays of the American Soccer League defeated the San Francisco Bay Blackhawks of the Western Soccer League for the American Professional Soccer League championship.
