The ATP Tour (known as ATP World Tour between January 2009 and December 2018) is the sole worldwide top-tier tennis tour for men organized by the Association of Tennis Professionals (ATP) founded in 1990 that replaced the earlier dual Grand Prix Circuit and WCT Circuit. The second-tier tour is the ATP Challenger Tour and the third-tier is the ITF Men's World Tennis Tour. The equivalent women's organisation is the WTA Tour.
