The Grande Oriente Español () is the oldest traditional Masonic body in Spain. It was founded in September 1889 by the unification of the Gran Oriente de España (GOdE) and the Gran Oriente Nacional de España (GONE). Among its Grand Masters was Diego Martínez Barrio, prime minister of Spain and founder of the Republican Union. The Grande Oriente was a member of the International Masonic Association, which was under the influence of the Grand Orient de France.
