Roberto Fonseca (born 1975, Havana) is a Cuban jazz pianist. From an early age, Fonseca was surrounded by music: his father was drum player Roberto Fonseca, Sr, his mother, Mercedes Cortes Alfaro, a professional singer (she sings on her son's most recent solo album, Zamazu), and his two older half-brothers from his mother's previous marriage to the pianist and musician Jesús "Chucho" Valdés are Emilio Valdés (drums) and Jesús "Chuchito" Valdés Jr. (piano).
