Marc Warren (born 20 March 1967) is an English actor, probably best known for his British television role as Danny Blue in Hustle and Elton Pope in the 2006 Doctor Who series episode "Love & Monsters".

Warren has worked in film, television, theatre and radio. He is a former member of the National Youth Theatre and trained at the East 15 acting school (although he didn't graduate). He began his career with a role in a 1988 production of Godspell which he won by writing to the producers, and went unrepresented until the following year.

Warren can also be heard on numerous television and radio adverts throughout the UK. Contrary to popular belief, Warren does not provide the voice for the animated gecko in the Geico insurance company commercials, which is in fact voiced by British actor Jake Wood.
