"El Choclo" (South American Spanish: meaning "The Corn Cob") is a popular song written by Ángel Villoldo, an Argentine musician.

[1] The piece was premiered in Buenos Aires in 1903 – the date appears on a program of the venue – at the elegant restaurant El Americano on Cangallo 966 (today Teniente General Perón 966) by the orchestra led by José Luis Roncallo.

In 2001 the hip-hop group Delinquent Habits made the song known to a new generation when they released "Return of the tres", which relies heavily on samplings from a Mariachi version of the classical tango.

In Russian, "El Choclo" serves as the melody for the well-known blatnaya pesnya (criminals' song) На Дерибасовской открылася пивная ("a beer bar opened up on De Ribas Street").

Argentine actress and singer Tita Merello performed El Choclo in the film La Historia del Tango (1949).
