The 2026 Cincinnati Open women’s singles final was the first all-American final at the event since 1970.
Coco Gauff and Jessica Pegula created the historic matchup, with Gauff winning 6–2, 6–4. The previous all-American women’s final in Cincinnati had occurred more than five decades earlier, making the 2026 meeting a significant milestone for U.S. tennis.
An all-American final means both finalists represented the United States in the singles championship match. It does not mean that every semifinalist or every player in the draw came from the United States.
The 1970 reference belongs specifically to the women’s singles final at Cincinnati. It should not be confused with the tournament’s founding date, the year the event became an Open-era tournament, or the date of an earlier American men’s final.
