Jenson Brooksby defeated Frances Tiafoe in the final, 6–4, 6–2 to win the singles tennis title at the 2025 U.S. Men's Clay Court Championships. It was his first ATP Tour title. He saved five match points across three separate matches en route to the title – one against Federico Agustín Gómez in the first qualifying round, three against Alejandro Tabilo in the second round, and one against Tommy Paul in the semifinals. Ranked as the world No. 507, Brooksby was the lowest-ranked quarterfinalist and beyond in the tournament's history, and the lowest-ranked ATP Tour finalist and champion on clay since 1990.
Ben Shelton was the reigning champion, but did not participate this year.
All eight quarterfinalists were Americans, marking the first time that all the quarterfinalists in an ATP Tour event were from the same country since the 1991 Prudential-Bache Securities Classic.
