The Cincinnati Open, historically known as the Cincinnati Masters, has one of the deepest histories on the professional tennis calendar.
Dating back to 1899, the tournament has produced champions from several generations of the sport, with legends such as Roger Federer, Serena Williams, Novak Djokovic and Rafael Nadal all among its winners.
The event has also evolved considerably over the decades. Today, the Cincinnati Open is one of the most important ATP Masters 1000 and WTA 1000 tournaments, traditionally serving as a major preparation event for the US Open.
The tournament’s official records list champions across four principal categories: men’s singles, women’s singles, men’s doubles and women’s doubles.
The history stretches back more than 125 years, although the women’s competition and the various doubles events have not been contested continuously throughout that entire period.
For the modern era, Cincinnati has become a particularly prestigious stop on the hard-court calendar. Winning there often provides an important confidence boost heading into the final Grand Slam of the season.

What about the 2026 Cincinnati Open?
The 2026 tournament is taking place from August 8-23, with the singles finals scheduled for Sunday, August 23. That means the men’s and women’s singles champions have not yet been determined at the time of writing.
The singles finals will feature Jessica Pegula against Coco Gauff in the women’s competition and Frances Tiafoe against Arthur Fils in the men’s event. Pegula reached the final by defeating defending champion Swiatek, while Gauff beat Sara Bejlek.
Fils defeated Flavio Cobolli and Tiafoe overcame Brandon Nakashima to complete the men’s final lineup.
The doubles competitions, meanwhile, are also part of the tournament’s long-running championship tradition, with the event’s official schedule placing the women’s doubles final on August 22 and the men’s doubles final on August 23.
So while Cincinnati’s record book already contains more than a century of champions, the 2026 edition is about to add several more names to that distinguished list.
With four major trophies at stake across singles and doubles, this year’s tournament will soon have its latest chapter in one of tennis’s oldest and most prestigious events.
