Dean Martin Gaffney (born 14 February 1978) is an English actor, known for his role as Robbie Jackson on the BBC soap opera EastEnders from 1993 to 2003 and 2017 to 2019; he also made guest appearances in 2004, 2010 and 2015. In 2006, he competed in the ITV series I'm a Celebrity...Get Me Out of Here!, and finished in fifth place.
Gaffney was born in Hammersmith, London. He attended St Mark's Catholic School, Hounslow, and later trained at the Sylvia Young Theatre School in Marylebone and the Corona Theatre School in Kew Bridge.
Gaffney's first appearance as Robbie Jackson in EastEnders aired in December 1993, and he remained in the role for eleven years. In 2003, executive producer Louise Berridge made the decision to axe Gaffney along with the actress Bindya Solanki, who played his on-screen girlfriend Nita Mistry. In a press report, Berridge commented, "we do feel that the characters have reached the end of their natural course in the show, and they will both be leaving in Spring 2003". Gaffney made a further appearance in the soap, returning for a brief visit in 2004 for the wedding of his on-screen half-sister Sonia Jackson (portrayed by Natalie Cassidy).
