2013 Sony Open Tennis – Men's singles

Andy Murray defeated David Ferrer in the final, 2–6, 6–4, 7–6(7–1) to win the men's singles tennis title at the 2013 Miami Open. He saved a championship point en route to his second Miami Open title.

Novak Djokovic was the two-time defending champion, but lost in the fourth round to Tommy Haas. Between 2011 and 2016, this was the only edition of the tournament that Djokovic did not win.

This was the first edition of the tournament not to feature an American in the quarterfinals, and also the first all-European quarterfinal lineup at the tournament.
