Defending champion Roger Federer defeated Novak Djokovic in the final, 7–6(7–1), 6–3 to win the men's singles tennis title at the 2015 Cincinnati Masters. He won the title without losing a set or having his serve broken for the second time, after 2012.

It was Djokovic's fifth runner-up finish without winning the title; he would eventually do so in 2018.
