Rey de Reyes 2011, was a professional wrestling pay-per-view (PPV) event produced by Asistencia Asesoría y Administración (AAA), that took place on March 18, 2011, at Plaza de Toros Monumental in Aguascalientes, Aguascalientes, Mexico. The event was the 15th event produced under the Rey de Reyes name and also the 15th time that the Rey de Reyes tournament was held.
The event featured several professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines.
