Tad Martin is a fictional character from the American daytime drama, All My Children. Tad was played by three actors, according to the age of the character: Matthew Anton, John E. Dunn, and Michael E. Knight. Knight has portrayed the role on and off from 1982 until the series finale in 2011. Tad represents the good on the show, often butting heads with "villains" like Adam Chandler. He is perhaps the best male friend to Erica Kane. His relationship with Dixie Cooney made them a favorite of fans, reaching supercouple status. Under secrecy, Knight returned for the first-season finale of Prospect Park's version of All My Children on September 2, 2013.
