Mason hosted the 2026 Cincinnati Open tournament site.
The event was held at the Lindner Family Tennis Center in Mason, Ohio. Mason lies north of Cincinnati, which explains why the tournament carries Cincinnati’s name even though the venue is outside the city itself.
The location has been associated with the tournament’s modern identity since the event moved to the Mason site. It provides the permanent courts and stadium infrastructure used for the combined ATP and WTA competition.
This geographic distinction is a common source of confusion. “Cincinnati Open” refers to the tournament, while “Mason” identifies the municipality where the matches were played. The 2026 event took place in the United States on outdoor hard courts.
