Son cubano (or just son) is a style of music that originated in Cuba and gained worldwide popularity in the 1930s. Son combines the structure and elements of Spanish canción and the Spanish guitar with African rhythms and percussion instruments of Bantu and Arará origin. The Cuban son is one of the most influential and widespread forms of Latin American music: its derivatives and fusions such as salsa and timba have spread across the world.

The word son (literally meaning 'sound' in Spanish) has also come to be used for other traditional rural musical styles of Spanish-speaking countries. For example, in Mexico the Son Jarocho of Veracruz and the Son Huasteco of the Sierra Huasteca constitute distinct popular musical styles. They are not derived from the Cuban son.
