The AAA Fusión Championship ("Campeonato AAA Fusión" in Spanish) was a professional wrestling championship promoted by the Asistencia Asesoría y Administración (AAA) promotion in Mexico. The first champion was crowned on March 17, 2013, when Fénix won a tournament for the title. On August 17, 2014, the title was unified with the AAA Cruiserweight Championship. The championship was generally contested in professional wrestling matches, in which participants execute scripted finishes rather than contend in direct competition.
