Mary Smith, also known as Mary the Punk, is a fictional character from the BBC soap opera EastEnders, played by Linda Davidson, from 5 March 1985 to 26 May 1988. Punk Mary is Walford's original wild child. She often makes life difficult for herself due to her stubborn, defensive nature and she tends to feel that everyone around her is out to get her. In fact, Mary is her own worst enemy and most of her misfortune is down to her irresponsible behaviour and her inability to heed good advice. Davidson's return to the soap for a single episode was announced in December 2018. She returns for the funeral of Doctor Legg (Leonard Fenton) in episode 5871, originally broadcast on 19 February 2019.
