Rafael "Rafa" Múñoz Pérez[a] (born 3 March 1988) is an Olympic swimmer from Spain.

On April 5, 2009, at the 2009 Spanish Championships, he swam a 22.43 in the long-course 50 butterfly, going under the existing World Record of 22.96 by South Africa's Roland Schoeman.

This time, however, was not recognized as the world record until 22 June, when the governing body of aquatic sports, FINA, finally accepted the controversial swimsuit he and many other swimmers had been wearing as they achieved such times.

[3] He was coached by Romain Barnier in France, as part of the Cercle des Nageurs de Marseille team.
