Eric William Dane (born November 9, 1972) is an American actor, most recently known for his role as Dr. Mark Sloan in Grey's Anatomy.

After appearing in a San Mateo High School's production of Arthur Miller's All My Sons, Dane decided to pursue a career in acting. He relocated to Los Angeles, where he played small roles in the television series Saved by the Bell, The Wonder Years, Roseanne, and Married With Children, among others. But in 2000, he was signed for a recurring role in Gideon's Crossing, and followed this with a two-season run in Charmed. His made-for-television movie credits included two biopics, Serving in Silence (about Margarethe Cammermeyer's experiences in the military), and Helter Skelter, in which he portrayed a member of the Charles Manson clan.

Dane's first major feature film appearance was in The Basket (1999). He also appeared in Zoe, Duncan, Jack & Jane, Sol Goode, Feast, Open Water 2, and X-Men: The Last Stand.
