Carlos Villagrán Eslava (born 12 January 1944) is a Mexican actor, comedian, and former journalist best known for playing Quico in the Televisa sitcom El Chavo del Ocho.

Villagrán started off as a photographer for the Mexico City newspaper El Heraldo, with this position leading him to become friends with screenwriter and future co-star Rubén Aguirre.

Aguirre had been hired by Chespirito (Roberto Gómez Bolaños) to play the role of Professor Jirafales in the then upcoming El Chavo del Ocho television series for Televisa.

Villagrán left the shows in 1978, for reasons never officially confirmed; speculation suggests it was because he and Chespirito were engaged in a legal battle over the rights of the Quico character.

For a brief time a local comic named Sergio Ramos was brought in as Don Cejudo to replace Valdés, but the show soon was taken off the air due to the difference in chemistry between the characters causing a decline in popularity.

On April 1st, 2000, in an El Chavo del Ocho special which reunited all the actors from the series to honor the career of Chespirito (except Ramón Valdés, Angelines Fernández, Raúl Padilla, Horacio Gómez Bolaños, who had all passed prior to the special, and Ana Lilian de la Macorra, who was unable to attend), Villagrán and Chespirito saw each other for the first time in twenty-two years and reconciled their differences.
