Esteban Salas y Castro (December 25, 1725 – July 14, 1803) was a Cuban composer of religious music. His compositions focused chiefly on vocal music, and are a fine representation of the late Baroque style. Although heavily influenced by French and Italian works of the period, his music is considered to incorporate an original Latin American component. Interest in his works was revived during the twentieth century following the rediscovery of many of his scores during the 1940s by the Cuban novelist and musicologist, Alejo Carpentier.
