Barbarito Díez (December 4, 1909 – May 6, 1995) was a Cuban singer who specialized in danzón. He began his career as the singer for Graciano Gómez and Isaac Oviedo's son group, before joining Antonio María Romeu's orchestra. As the lead vocalist for Romeu's ensemble for 20 years, he established himself as one of the main exponents of the sung danzón. He continued singing with his own charanga, as well as other groups, for another 30 years. He also toured and recorded in Venezuela and Puerto Rico before retiring in the early 1990s, when complications from diabetes prevented him from performing and eventually resulted in his death in 1995. A naturally-gifted tenor, he was known for his sense of rhythm, correct diction and romantic style.
