Craig Ferguson (born 17 May 1962) is a Scottish-American television host, stand-up comedian, writer, actor, director, author, and producer. He is the host of The Late Late Show with Craig Ferguson, an Emmy Award-nominated, Peabody Award-winning late-night talk show that airs on CBS. In addition to hosting that program and performing stand-up comedy, Ferguson has written two books: Between the Bridge and the River, a novel, and American on Purpose, a memoir. He became a citizen of the United States in 2008.

Before his career as a late-night television host, Ferguson was best known in the United States for his role as the office boss, Nigel Wick, on The Drew Carey Show from 1996 to 2003. He also wrote and starred in three films, directing one of them.

Ferguson was born in the Stobhill Hospital in the Springburn district of Glasgow, Scotland to Robert and Janet Ferguson, and raised in nearby Cumbernauld, growing up "chubby and bullied". When he was six months old, he and his family moved from their Springburn apartment to a council house in Cumbernauld. They lived there as Glasgow was re-housing many people following damage to the city from World War II. Ferguson attended Muirfield Primary School and Cumbernauld High School. At age sixteen, Ferguson dropped out of Cumbernauld High School and began an apprenticeship to be an electronics technician at a local factory of American company Burroughs Corporation.
