OTI Festival, often known simply as La OTI, was an international song competition, organised annually between 1972 and 2000 by the Organización de Televisión Iberoamericana (OTI), featuring participants representing primarily Ibero-American countries. Each participating OTI member broadcaster submitted an original song primarily in Spanish or Portuguese to be performed on live television and transmitted to all OTI broadcasters via satellite. It was preceded by the Festival Mundial de la Canción Latina, held in 1969 and 1970 in Mexico.
