Steven Weber (born March 4, 1961) is an American actor.

This Queens-born actor has certainly proven himself adept at everything from quirky comedy to flat-out melodrama. Born on March 4, 1961, to a Borscht Belt comic and a nightclub singer, Weber was already appearing in TV commercials by elementary school age. He later studied at the High School of the Performing Arts in New York and graduated from New York State University. The fair-haired, fair-skinned actor worked a series of menial jobs during his salad days as a struggling thespian (custodian, elevator operator, singing waiter) until earning his break on TV in a presentation of one of Mark Twain's stories. Quickly making his film debut in the popular comedy Flamingo Kid, The (1984), he nabbed a running role on the soap opera "As the World Turns" (1956) a year later. On the set he met first wife Finn Carter, another co-star on the daytime drama. Steven stayed put for a year then went on to gain recognition in more offbeat and/or prestigious productions on film and primetime TV. He played a rock star in the thoroughly offbeat foreign-made film Ángeles, Los (1990) and showed real command as John F. Kennedy in the epic miniseries "Kennedys of Massachusetts, The" (1990) (mini). That same year TV stardom came his way with the sitcom "Wings" (1990). Co-starring with Tim Daly as Brian Hackett, the looser, goofier more aimless half of the brotherly team who co-owned a one-plane, Nantucket-based airline, the actors' chemistry, not to mention a terrifically eclectic supporting cast, kept the show on a steady course for seven seasons. Easily typed now as a genial, lovable loser type, Weber faced the prospect of severe pigeon-holing. So during the show's off season, he started showing up in more serious roles. He suffered at the hands of the deranged Jennifer Jason Leigh in Single White Female (1992); appeared in a second chiller with Temp, The (1993); and made a cameo in the highly depressing, award-winning Leaving Las Vegas (1995). He truly impressed both critics and audiences alike as the complex title character in Jeffrey (1995), a gay romantic film comedy, and then completely defied all odds by starring in an epic TV-movie version of Stephen King (I)'s horror classic "Shining, The" (1997) (mini), seizing the role inherited from Jack Nicholson and brilliantly making it his own while earning a Saturn award for his chilling efforts. By the time "Wings" came to an end in 1997, Weber had divorced wife Finn (they had no children) and married actress/TV executive Juliette Hohnen. The couple married on July 9, 1995 and have since had two children, Jack and Alfie. Since then Steven has remained quite productive. He and Laura Linney were selected to play the TV-movie leads in the popular A.R. Gurney theater piece Love Letters (1999) (TV). While other TV series comebacks have fared less well, including the short runs of "Cursed" (2000) and "D.A., The" (2004), Steven bounced back in other venues. In 2002, he joined the cast of the smash Broadway musical "The Producers," taking over the nebbish Matthew Broderick (I) role. In 2004, he went to London to appear on stage with Kevin Spacey and Mary Stuart Masterson in "National Anthems." Other plays over the years have included "Throwing Your Voice," "Something in the Air" and "Design for Living." In addition to giving voice occasionally to a few animated film and TV characters, he returned fruitfully to Stephen King (I) territory in 2006 with two major TV projects.
