Stuart Townsend (born on 15 December 1972 in Howth, County Dublin) is an Irish actor and director.

Like fellow Irish actor Colin Farrell, he attended the Gaiety School of Acting in Dublin where he made his non-professional stage debut in the school's production of Tear Up The Black Sail. His professional stage debut was in 1994's True Lines, directed by John Crowley, who later directed Intermission. True Lines was first performed in Kilkenny; it later moved to the Dublin Theatre Festival and on to Bush Theatre in London.

Townsend's early movie roles were in Irish short films such as "Godsuit" and "Summertime". His first part in a feature length film was Trojan Eddie, a 1996 UK/Irish co-production. In 1997 he landed a lead role in the British film Shooting Fish.
