The Thin Blue Line is a British sitcom starring Rowan Atkinson set in a police station that ran for two series on the BBC from 1995 to 1996. It was written by Ben Elton.

Detective Sergeant Tommy Murphy is a maverick cop with a dark past. After failing a psychiatric assessment, he is given one last chance by his boss and given a dangerous undercover assignment. Murphy is a loner with little to lose and deals with everything on his own terms. This time around, however, Murphy has an ally in Detective Inspector Annie Guthrie.
