Theodore Martin "Ted" McGinley (born May 30, 1958) is an American actor. He is perhaps best known for his role as Jefferson D'Arcy on the television series Married... with Children, and as Charley Shanowski on the former ABC sitcom Hope & Faith.

McGinley began his career in modeling. After a casting director spotted a picture of him in GQ, he was cast in comedy series Happy Days, as Roger Phillips (nephew of the Cunninghams), a role he played from 1980 until 1984. During the run of Happy Days, he landed a role in the 1982 comedy Young Doctors in Love. After Happy Days ended in 1984, McGinley appeared in Revenge of the Nerds where he played Stanley Gable, the head of the jock-run Alpha Beta fraternity and the primary antagonist of the Lambda Lambda Lambda nerd fraternity. He went on to appear in regular roles in television series including The Love Boat and Dynasty. He then went into the role of Jefferson D'Arcy on Married... with Children from 1991 to 1997. From 2003 until 2006, he played Charley Shanowski on Hope & Faith. He is of Irish descent.

McGinley has been called the patron saint of "jumping the shark" by jumptheshark.com founder Jon Hein. This is a reference to the popular and enduring shows which have featured him in their declining years. Such shows include Happy Days, The Love Boat and Dynasty. Hein writes that this is not a comment "on Ted's fine acting skills" and that "he has a great sense of humor about it, too". In one episode of Married... with Children (a show that stayed on the air for 6 seasons after McGinley's addition to the cast) McGinley himself spoofed this fact by momentarily breaking the fourth wall by asking Al "Another picture, captain? I mean, Fonzie? ....Al?"
