Which pair won the 2026 US Open mixed doubles title?

Karolína Muchová and Jakub Menšík won the 2026 US Open mixed doubles title.

The all-Czech team defeated Switzerland’s Belinda Bencic and Italy’s Flavio Cobolli in the championship match. Muchová and Menšík won the final 6–3, 1–6, [10–6], with the deciding match played as a 10-point match tiebreak.

The 2026 mixed doubles competition used a special shortened format in its early rounds, designed to attract high-profile singles players and create a faster event. The final used traditional sets to six games before the deciding match tiebreak.

The victory was notable because Muchová is best known for her singles career, while Menšík is a young Czech player who had already become a significant presence on the ATP Tour. Together, they gave the Czech Republic the mixed doubles championship in New York.
