Katie McGrath is an Irish actress best known for her starring role as Morgana in the fantasy drama television series The Adventures of Merlin (also known simply as Merlin), from 2008-2012.
McGrath graduated in History at Trinity College, Dublin. She wanted to work in fashion journalism and took a job at Image magazine before becoming a wardrobe assistant on the set of The Tudors.
While working on The Tudors, McGrath was advised to try acting, so she sent photographs around Irish agents. She then won a small role in the series.
She also appeared in the feature films Eden and Freakdog, before being cast in Merlin.
In 2013, Katie reunited with her The Tudors co-star and close friend Jonathan Rhys Meyers in NBC and Sky Living's horror drama TV series Dracula, in the role of Lucy Westenra.
