ATP Tour

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 equivalent women's organisation is the WTA Tour.

The Grand Slam tournaments, the Olympic tennis tournament, the Davis Cup, and the entry-level ITF World Tennis Tour do not fall under the purview of the ATP, but are overseen by the International Tennis Federation (ITF) instead and the International Olympic Committee (IOC) for the Olympics.

In these events, however, ATP ranking points are awarded, with the exception of the Olympics.

Players and doubles teams with the most ranking points (collected during the calendar year) play in the season-ending ATP Finals, which, from 2000–2008, was run jointly with the ITF.
