The women's singles final at the 2026 Cincinnati Open ended 6–2, 6–4 in Coco Gauff's favor.
Gauff defeated Jessica Pegula in two sets to claim the women's singles championship. Gauff controlled the opening set 6–2 and then completed the victory with a 6–4 second set. Because the match ended in straight sets, no deciding set was needed.
Both finalists were American and entered the tournament among the top four seeds. Gauff was seeded No. 4, while Pegula was No. 3. Their final was therefore a meeting between two leading players in the women's draw rather than an unseeded surprise finalist and a top seed.
The match was part of the WTA 1000 event held at the Lindner Family Tennis Center in Mason, Ohio. The 2026 Cincinnati Open ran from 13 to 23 August and was played on outdoor hard courts. Gauff's win gave her a second Cincinnati Open singles title.
