Eric Harry Timothy Mabius (born April 22, 1971) is an American actor. He is known for his film and television roles, including Ugly Betty and Cruel Intentions.

Of Irish and Polish descent, Eric Mabius was born on April 22, 1971. He grew up moving almost constantly. Upon graduating from high school he attended the renowned arts school, Sarah Lawrence College. Immersing himself in acting, writing and film theory, college became the jumping-off point for Mabius' first roles in the theater in smaller Off-Broadway productions. He landed his first film role as the object of Heather Matarazzo's affection, the teen rock star, in Todd Solondz's Sundance Grand Prize Winner, Welcome to the Dollhouse (1995). Mabius has appeared in more than 27 films - seven of which screened at Sundance - and over a dozen television projects. His credits include roles in many genres, ranging from action (Resident Evil (2002) and Extreme Team, The (2003)), drama (Cruel Intentions (1999)), comedy ('Welcome to the Dollhouse' and Wirey Spindell (2000)), mystery (Minus Man, The (1999)), horror (Crow: Salvation, The (2000) and Black Circle Boys (1997)), and romance (Splendor (1999) and Dancing at the Harvest Moon (2002) (TV)). Showtime's groundbreaking series, "L Word, The" (2004) and ABC's "Eyes" (2005) are but a few more in a long line of unique and varied projects he has chosen that have achieved critical and audience acclaim.

A rising actor with an intense screen presence, Eric Mabius brings a varied background to his work. Born of Polish, Irish, and Austrian ancestry, he was born in Pennsylvania, but spent much of his life in Massachusetts. A graduate of Sarah Lawrence College, he first came to the attention of movie fans with his film debut in Welcome to the Dollhouse (1995). Since then, he has taken on a wide variety of roles, avoiding being typecast. He earned favorable notice for his performance as a high school gang leader in Black Circle Boys (1997). More roles followed, his best known being in the box office smash Cruel Intentions (1999), where he plays a prep school athlete who gets blackmailed. He got a starring role in Crow: Salvation, The (2000), a sequel to the Brandon Lee (I) film from a few years earlier. Another horror film which he appeared in was the science fiction action film Resident Evil (2002), in which he plays a policeman in the future. His most prominent role to date was in the Showtime TV drama "L Word, The" (2004), which won him a new audience. He starred in another TV series, the high tech drama "Eyes" (2005), but although the series was well received, it never found an audience. But his standing wasn't damaged, and he continues to have a devoted fan base, particularly among audiences of independent films. Currently, he stars in the surprise hit series "Ugly Betty" (2006), playing a womanizing executive. While he greatly appreciates his fans, he is a private person who doesn't seek the limelight. Thus, he doesn't show up at events which draw tabloid photographers. In February of 2006, he married his girlfriend of five years, interior designer Ivy Sherman, in New Orleans.
