The Atlanta Open is a men's professional hard court tennis tournament which is part of the ATP Tour. Inaugurated in 1988 in Indianapolis, it has been played in Atlanta, United States since 2010.
The tournament has its origins in the Indianapolis Tennis Championships, which had been held in Indianapolis since 1921. With the advent of the Open Era in 1968, the Indianapolis tournament became the new home for the US Men's Clay Court Championships, held on clay courts.
In 1974, the new Indianapolis Racquet Club facility was built, and as the tournament grew in importance, the new Indianapolis Sports Center, later to be called the Indianapolis Tennis Center, was built in 1979. The US Men's Clay Court Championships was last hosted in Indianapolis in 1987, after which 14 of the facility's 18 clay courts became hard courts covered with DecoTurf II, the same surface area then used for the US Open. In 1988 the US Men's Clay Court Championships were moved to Charleston.
In 1912 there was the first edition played at the Atlantic Station, a large multi-purpose shopping complex located in downtown Atlanta, and the tournament took the name BB&T Atlanta Open from the new sponsor. In 2015 the tournament was bought by the New York company GF Sports and Entertainment. The 2020 edition was canceled due to the COVID-19 pandemic, play returned in 2021 with a new sponsor and the tournament was renamed the Truist Atlanta Open.
Atlanta had previously hosted tournaments on the major men's circuit, between 1969 and 1986 the Atlanta Open of the same name was held with various interruptions, which was part of the WCT and Grand Prix circuits and saw among its participants John McEnroe, Stan Smith, Ilie Năstase, Rod Laver and John Newcombe.
