Arthur Steven Lange (born October 11, 1967) is an American television and movie actor. Lange was born in Union, New Jersey.

After being held back from graduating high school Lange had many odd jobs, but scored big in 1995 when he landed a recurring role in Fox's hit sketch comedy MADtv. At that time, Lange used his Chris Farley-esque appearance to gain him the upper hand in gigs. However, just two years later he would be fired.

MADtv staff, upon noticing Lange's apparent prolonged tardiness to the set, and deteriorating physical appearance questioned him about his drug use and about possible rehab. When Artie still adamantly refused, the staff then contacted the police. When the police finally showed up, Lange took off on foot, with the Los Angeles Police Department and MADtv staff in tow. Jumping fences and running through backyards the hefty Lange was eventually tackled by a police officer. Lange admitted during interviews on the Howard Stern Show that he did the stupidest thing that a person can do, which is punch a police officer. And after being manhandled by the cops, he was charged with the possession of cocaine, assaulting an officer, and possessing an open alcoholic container in his car among other charges.

After a short time in jail and rehab, Lange began capitalizing on his friendship with Norm MacDonald, in which he appeared in MacDonald's movie Dirty Work (1998), and also on his ABC comedy sitcom The Norm Show (1999). Lange also has starred in Mystery Men (1999), and The Bachelor (1999) before landing a full-time spot in the Howard Stern Show after long time co-host Jackie Martling quit. In addition to Stern, Lange also still works in movies and does stand up at comedy houses around the United States.
