Desmond Harrington (born October 19, 1976) is an American actor, who gained fame through movies like The Hole, Wrong Turn and Ghost Ship.

Harrington was born in Savannah, Georgia and moved with his family from Savannah to The Bronx at the age of 3. He attended Catholic school and eventually graduated from Fordham Preparatory School, a Jesuit high school and as a hyperactive student, he caused problems. After high school, he attended Manhattan College, but was thrown out after only 6 weeks. Afterwards, he worked in various other occupations before pursuing acting which included working at a brokerage firm, a deli, in construction and landscaping and as a bartender, mostly to pay for acting classes with John Strasberg. Through acting, Desmond had found an appropriate outlet for his hyperactive behavior.

His first role was playing Aulon in Luc Besson's The Messenger: The Story of Joan of Arc. He soon later grabbed prominent roles in films such as The Hole, Ghost Ship and Wrong Turn.

He resides in Los Angeles in a one-bedroom apartment with his dog Etta.

Desmond Harrington was born in Savannah, Georgia, but when he was 3-years old, his parents decided to move back to their birth place, The Bronx, New York. Growing up in the Bronx, Desmond attended Catholic schools for 12 years St. Margaret's of Cortona for elementary school and Fordham Prep for high school. Desmond found trouble in and out of school throughout his formative years. After high school, Desmond attended Manhattan college for 6 weeks before dropping out. With no real sense of direction, he took jobs as a laborer, landscaper, a cold caller at a brokerage firm, and finally a bartender in Manhattan, where a co-worker invited him to attend an acting class. Over the years, Desmond has appeared in dramas and comedies alike, and has always delivered the goods.
