The 2026 Cincinnati Open was played in Mason, Ohio.
Mason is a city in Warren County, north of Cincinnati and within the Cincinnati metropolitan area. The tournament keeps the Cincinnati name because of its regional heritage and audience, even though the grounds are not inside Cincinnati’s municipal boundaries.
The 2026 edition took place at the Lindner Family Tennis Center, the established home of the tournament. The site hosted the event’s men’s and women’s singles and doubles competitions during the August 13–23 schedule.
This geographic detail is often confused because the tournament title sounds like a city address. In tennis, event names frequently reflect a nearby major city, metropolitan area, sponsor, or historical identity rather than the exact municipality. Here, “Cincinnati Open” refers to the tournament, while Mason identifies the host city.
