Brad Barron Renfro (July 25, 1982 – January 15, 2008) was an American actor. He made his film debut at age 11 with a starring role in The Client (1994). Renfro went on to appear in 21 feature films and won several awards.

Prior to being cast in The Client, Renfro had no acting background and was living with his grandmother in a trailer park. Wanting to cast a "tough kid" who had the life experience to understand the character he would portray, director Joel Schumacher chose Renfro to play the role of Mark Sway. Renfro soon attracted a large fanbase as he continued to star in movies like The Cure, Tom and Huck, Sleepers, Apt Pupil, Bully and Ghost World.

Beginning in the late 1990s, Renfro experienced difficulties in his private life, including drug addiction and a series of arrests. He died at age 25 of acute heroin and morphine intoxication.
