Rafael Muñoz

Rafael "Rafa" Múñoz Pérez (born 3 March 1988) is an Olympic swimmer from Spain. He competed for the Spanish Olympic team at the 2008 Olympic Games. He was born in Córdoba.

On 5 April 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. His world record was broken by Andriy Govorov in July 2018.

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