"Cielito Lindo" is a popular traditional song of Mexico, written in 1882 by Quirino Mendoza y Cortés (c. 1859–1957). In recent decades it has come to be widely known as a theme song for Mexicans, particularly in international circumstances, like the soccer championship World Cup, where Mexican fans sang it to the Mexican national team.

The melody was used as the basis for a popular English-language song, "You, Me, and Us," which became a hit for Alma Cogan in the United Kingdom in 1957.
