Lawrence Donald Clark (born January 19, 1943) is an American film director, photographer, writer and film producer who is best known for his controversial teen film Kids (1995) and his photography book Tulsa. His work focuses primarily on youth who casually engage in illegal drug use, underage sex, and violence, and who are part of a specific subculture, such as surfing, punk rock, or skateboarding. Directors such as Gus Van Sant and Martin Scorsese have stated that they were influenced by Clark's early photography, according to Peter Biskind's book Down and Dirty Pictures.

Film critics who do not find social or artistic value in Clark's work have labeled his films obscene, exploitative, and borderline child pornography because of their frequent and explicit depictions of teenagers using drugs and having sex. However, Roger Ebert was a fan of his work, giving positive reviews to Kids, Another Day in Paradise, Bully, and Wassup Rockers.
