Lucy Benjamin (born 25 June 1970) is a British actress.

Born Lucy Jane Baker in Reading, Berkshire, England, she took the stage name of Benjamin after her brother. Her first acting role was as a child actor in Doctor Who in 1983. In 1989 she starred in the children’s television programme Press Gang, where she played ‘Julie Craig’ until 1993. In 1995 she appeared in the Rik Mayall comedy Bottom. However she is probably best known for her role as Lisa Fowler in the BBC soap opera EastEnders which she played from 1998-2003.

During her time on EastEnders she was involved in one of the soap’s most renown and highly anticipated storylines, known as Who shot Phil? (2001). The storyline centred around the shooting of her on-screen lover Phil Mitchell and who, out of the many potential candidates, actually performed the dastardly deed. Several suspects ermerged and the audience was kept in the dark as to who the actual murderer was for many weeks. Lucy’s character was eventually unveiled as the shooter. However, despite her heavy involvement in the memorable plot, Lucy was asked to leave the soap in 2002 as producers felt her character had run its course and there was no story options left for her at present. She was asked back for a short period in 2003 however, to help with the oncoming exit of Steve McFadden, who was taking a hiatus from the hit soap.

Lucy’s offscreen relationship with EastEnders co-star Steve McFadden was much publicised in the British tabloid press during her time on the show. The relationship allegedly ended after McFadden was caught cheating on her with an ex-lover and the pair split in 2003.

Since leaving Eastenders Lucy has appeared in the BBC television programme ‘The Afternoon Play’, and the BBC hospital drama Casualty.

In April 2006 it was reported in The Daily Mirror that Lucy is in talks with EastEnders about reprising the role of Lisa Fowler, but it has yet to be confirmed by the BBC.
