Los Zafiros (The Sapphires) were a Cuban close-harmony vocal group working from 1961–1970. The group was part of the filín (feeling) movement, inspired by American doo-wop groups such as The Platters. Their music was a fusion of Cuban genres, such as the bolero, with doo-wop, ballads, R&B, calypso, Bossa Nova and rock.

Los Zafiros were formed in Cayo Hueso, Havana in 1961, by Néstor Milí Bustillo, with the members:
