Sheen was born Carlos Irwin Estévez in New York City, the youngest son and third of four children of actor Martin Sheen and artist Janet Templeton. Sheen has two older brothers, Emilio Estévez and Ramon Estévez, and a younger sister, Renée Estévez, all actors. His parents moved to Malibu, California, after Martin's Broadway turn in The Subject Was Roses. His first movie appearance was at age nine in his father’s 1974 film The Execution of Private Slovik. Sheen attended Santa Monica High School in Santa Monica, California, where he was a star pitcher and shortstop for the baseball team.
During his days at Santa Monica High School he showed an early interest in acting, making amateur Super-8 films with his brother Emilio and school friends Rob Lowe and Sean Penn, at the time still using his birth name. A few weeks before graduation, Sheen was expelled from school for poor grades and attendance. Deciding to become an actor, he took the stage name Charlie Sheen. His father had adopted it in honor of the Catholic archbishop and theologian Fulton J. Sheen.
