The ATP is the governing body of the men's professional tennis circuits - the ATP Tour, the ATP Challenger Tour and the ATP Champions Tour. With 64 tournaments in 31 countries, the ATP Tour showcases the finest male athletes competing in the world’s most exciting venues. From Australia to Europe and the Americas to Asia, the stars of the 2021 ATP Tour will battle for prestigious titles and FedEx ATP Rankings points at ATP Tour Masters 1000, 500 and 250 events, as well as Grand Slams (non ATP events).
