The 1971 World Championship Tennis circuit was one of the two rival professional male tennis circuits of 1971. It was organized by World Championship Tennis (WCT). Points were awarded to players based on their tournament results (ten points for the tournament winner, seven points for the runner–up, four points for the semifinalists, two points for the quarterfinalists and one point for reaching the second round). The circuit included twenty regular events and a WCT circuit final taking place in Houston/Dallas in November for the eight players with the highest points total. Each tournament had a minimum prize money of $50,000.
