"El Choclo" (South American Spanish: meaning "The Corn Cob") is a popular song written by Ángel Villoldo, an Argentine musician. Allegedly written in honour of and taking its title from the nickname of the proprietor of a nightclub, who was known as "El Choclo". It is one of the most popular tangos in Argentina.

The piece was premiered in Buenos Aires, Argentina 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.

"El Choclo" has been recorded (without vocals) by many dance orchestras, especially in Argentina. A number of vocal versions were recorded in the United States in 1952, but the most popular was the one by Georgia Gibbs, which reached #1 on the Billboard chart under the name "Kiss of Fire". Tony Martin's version reached #6, Toni Arden's #14, Billy Eckstine's #16, Louis Armstrong's #20, and Guy Lombardo's version reached #30. There are Spanish versions of "Kiss of Fire" by Connie Francis and Nat King Cole. In 1953 Olavi Virta and Metro-Tytöt released a Finnish version, titled "Tulisuudelma", which means "Kiss of Fire". The Finnish words, by "Kullervo" (Tapio Kullervo Lahtinen), closely follow the English. 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. The latest edition to this tune is included in the 2013 production by 7 Notas Music Designers of "Red Soul" by Manee Valentine.
