1991 Wimbledon Championships – Men's singles

Michael Stich defeated Boris Becker in the final, 6–4, 7–6^(7–4), 6–4 to win the gentlemen's singles tennis title at the 1991 Wimbledon Championships. It was his first and only major singles title.

Stefan Edberg was the defending champion, but lost in the semifinals to Stich. Stich won the match 4–6, 7–6^(7–5), 7–6^(7–5), 7–6^(7–2). This match was notable for Edberg holding serve in all 23 of his service games during the match, but still losing. The one and only service break of the entire match was in the fifth game of the first set, with Stich serving at 2–2 in that first set. This defeat prevented Edberg and Becker contesting the final for a fourth straight year.

Andre Agassi competed in Wimbledon for the first time since 1987, losing in the quarterfinals to David Wheaton. Agassi had previously refused to play Wimbledon from 1988 to 1990, in protest of the All England Club's all-white dress code.

This was the first year in Wimbledon history where there was play on the Middle Sunday, due to bad weather in the first week.
