The Cincinnati Open is an annual professional tennis event held in Cincinnati, United States. It is played on outdoor at the Lindner Family Tennis Center in Mason, Ohio, and is held in August. The event started on September 18, 1899, and is the oldest tennis tournament in the United States still played in (or near) its original city. From Club Court to Center Court by Phillip S. Smith, page 3 (2008 Edition; ). It also is the third largest tennis event in the United States, after the US Open and the Indian Wells Open. It is one of the ATP Masters 1000 tournaments on the ATP Tour, and one of the WTA 1000 tournaments on the WTA Tour.
In 1903, the tournament was moved to the Cincinnati Tennis Club, where it was primarily held until 1972. In 1974, the tournament was nearly dropped from the tennis calendar but moved at the last moment to the Cincinnati Convention Center, where it was played indoors and, for the first time since 1919, without a women's draw. In 1975, the tournament moved to the Coney Island amusement park on the Ohio River, and the tournament began to gain momentum again.
In 1979 the tournament moved to Mason where a permanent stadium was built and the surface was changed from Har-Tru clay to hardcourt (DecoTurf II.). Later, two other permanent stadia were constructed, making Cincinnati the only tennis tournament outside the four Grand Slam events with three stadium courts – Center Court, Grandstand Court and Court 3. A new Court 3 was built in 2010, increasing the number of stadium courts to four, with the existing Court 3 renamed Court 9. The women's competition was reinstated in 1988 for one year, and then again in 2004 when the organizers, with the help of the Octagon sports agency, bought the Croatian Bol Ladies Open and moved it to Cincinnati.
Between 1981 and 1989 it was a major tournament on the men's Grand Prix Tennis Tour and part of the Grand Prix Super Series.
In August 2008, the men's tournament was sold to the United States Tennis Association, the owners of the US Open.
In 2002, the tournament was sponsored for the first time by Western & Southern Financial Group, with the company continuing its sponsorship until at least 2016. In 2011 the men's and women's tournaments were played in the same week, and the name changed from the "Western & Southern Financial Group Masters and Women's Open" to the "Western & Southern Open".
In 2022, the tournament was sold by the USTA to Ben Navarro's Beemok Capital; in 2023, the tournament proposed an additional $22.5 million in state funding to help cover a proposed $150 million expansion to the Lindner Family Tennis Center, which included plans for the Cincinnati Open to expand to a 12-day format with a 96-player draw (joining the Indian Wells Open, Madrid Open, and Miami Open) and add additional programming. In May 2023, rumors emerged that Beemok was considering relocating the tournament to a proposed $400 million tennis complex in Charlotte, North Carolina. Beemok denied that relocation was being considered, stating, "We've had productive conversations with state and local representatives in Mason and the surrounding area and have made considerable efforts to develop a potential master plan to expand the event in its current location." In June 2023, the city proposed a $15 million commitment and other economic incentives to keep the tournament in Mason, while State Senator Steve Wilson proposed a $25 million contribution and a $1 billion "super-capital improvement fund" for a state budget proposal.
In October 2023, Beemok announced that the tournament would remain in Mason and expand to a 12-day format for 2025, with both draws expanding from 56 to 96 players. With the changes, Western & Southern exited its title sponsorship agreement, and the tournament returned to the "Cincinnati Open" name. The tournament also changed its sponsorship model to incorporate six "cornerstone" sponsors—including Western & Southern, Credit One Bank, Fifth Third Bank, Great American Insurance Group, Kroger, and Procter & Gamble—which would have activations and branding across the tournament.

In 2009, the tennis tournament announced a $10 million upgrade to the facility, including the construction of a West Building to add space for players, media and fans. The new building, which opened in mid-2010 and is named the Paul M. Flory Player Center, is approximately twice as high as the previous West Building, rising above ground level and above the court level.
In 2010, the tournament announced plans to expand the grounds by more than 40% and add six new courts. One of those courts is Court 3, which serves as the third television court, while another court has seating for 2,500. A new ticket office, entry plaza, food court and exhibit areas also were added.
In June 2020, due to the COVID-19 pandemic, the tournament temporarily relocated to the Billie Jean King National Tennis Center in New York City to reduce unnecessary player travel by centralizing the tournament and the U.S. Open at one venue.
The venue hosts additional events including the Atlantic 10 Conference Tennis Championships, the Ohio Athletic Conference Tennis Championships, and both the boys' and girls' OHSAA state tennis championships, and has hosted an Association of Volleyball Professionals event, concerts, charitable events, and numerous regional and national junior tennis events.
Because of intentional design choices for the Lindner Family Tennis Center, the Cincinnati Open is known as one of the more intimate environments for player-fan interaction. The layout of the facility promotes fan interaction as players walk from court to court among the fans, and the tournament publicizes player practice times on the numerous courts.
