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 and the Telerey sitcom ¡Ah qué Kiko!.
He went on to write for a local newspaper in Mexico City. As a writer, he became friends with screenwriter and future co-star Rubén Aguirre. Aguirre was hired by Chespirito (Roberto Gómez Bolaños) to play Professor Jirafales in the upcoming El Chavo del Ocho Televisa television series. Aguirre held a party for family and friends at his house, and Villagrán impressed him after expanding his cheeks out of proportion during one of the party's comic steps. As a matter of a fact, that movement would later become a trademark of the character he'd play in El Chavo.
Aguirre recommended Villagrán to Chespirito, and Villagrán was given the Quico character in the show. He also appeared on Chespirito's other hit show, El Chapulín Colorado. Both of Chespirito's shows became major international hits all over Latin America and in the United States, Spain, and other countries. Villagrán acquired great fame with these shows.
