Pete Sampras was the defending champion, but he retired earlier in the year.

Andy Roddick claimed his first and only Grand Slam title, defeating Juan Carlos Ferrero, 6–3, 7–6(7–2), 6–3, in the final. Roddick is the most recent American male singles player to win the US Open singles title as well as any other Grand Slam title.

This was the first US Open where Rafael Nadal appeared in the main draw.
