The 1974 World Championship Tennis (WCT) circuit was one of the two rival professional male tennis circuits of 1974, the other being the Grand Prix circuit. It was organized by World Championship Tennis (WCT). It was the fourth edition of the WCT circuit and a total of 84 players participated. All players took part in the opening U.S. Pro Indoor tournament in Philadelphia and afterwards were divided into three groups (red, blue and green) of 28 players, with each group playing eight further tournaments. The season final was played in Dallas by the eight best performers, the top two of each group plus the next two highest point winners, and was won by Australian John Newcombe who defeated Björn Borg from Sweden in four sets (4–6, 6–3, 6–3, 6–2).
