"Feliz Navidad" is a Christmas song written in 1970 by the Puerto Rican singer-songwriter José Feliciano.[1] With its simple Spanish chorus (the traditional Christmas/New Year greeting, "Feliz Navidad, próspero año y felicidad" meaning "Merry Christmas, a prosperous year and happiness") and equally simple English verse "I wanna wish you a Merry Christmas from the bottom of my heart", it has become a classic Christmas pop song in the United States, throughout the Spanish-speaking world and internationally.

Feliciano's version of "Feliz Navidad" (in which he plays both an acoustic guitar and a Puerto Rican cuatro) is one of the most downloaded and aired Christmas songs in the United States and Canada. The addition of the horns as a final touch was the idea of producer Rick Jarrard. It was also recognized by ASCAP as one of the top 25 most played and recorded Christmas songs around the world.[2]
