Roger Federer defeated Andy Roddick in the final, 5–7, 7–6(8–6), 7–6(7–5), 3–6, 16–14 to win the gentlemen's singles tennis title at the 2009 Wimbledon Championships.

This was Federer's eleventh grass court men's singles title, surpassing Sampras' Open Era record.

Notably, Roddick lost despite having his serve broken only once, in the last game of the match.

Rafael Nadal was the reigning champion, but withdrew from the tournament due to knee tendinitis.

This was the first major appearance of future ATP Finals champion Grigor Dimitrov, who retired in the first round against Igor Kunitsyn.
