Eric Cameron Stoltz (born September 30, 1961) is an American actor. He is known for playing either sensitive misfits (Mask, Kicking and Screaming, The Waterdance) or sociopathic criminals (Killing Zoe). He was nominated for a Golden Globe Award for Best Supporting Actor in a Motion Picture for Mask.

Stoltz was born in Whittier, California, the son of Evelyn B. (née Vawter), a violinist and schoolteacher who died in 1994, and Jack Stoltz, an elementary school teacher. He has two older sisters, Catherine Stoltz (1954) and Susan R. Stoltz (1957). Eric was raised in both American Samoa and Santa Barbara, California, where, as a child, he once earned money playing piano for local musical theatre productions. He attended the University of Southern California, where he dropped out in his junior year.

In the 1970s Stoltz joined a repertory company that did 10 plays at the Edinburgh Festival in Scotland, UK. He returned to the states in 1981 where he studied with Stella Adler and Peggy Feury in New York, and soon appeared in his first film, Fast Times at Ridgemont High (1982). Originally cast as Marty McFly in Back to the Future (1985), he was replaced after six weeks of filming, when Michael J. Fox (the director's first choice for the role) agreed to divide time between the movie and his television sitcom, Family Ties. The director, Robert Zemeckis, has said that while Stoltz provided an admirable performance, it lacked the humorous feel that Zemeckis was looking for. Some of the original footage (shots where Stoltz doesn't appear, but was on set) was used in the film.
