Reno 911! is an American comedy television series on Comedy Central that ran from 2003 to 2009. It is a mockumentary-style parody of law enforcement documentary shows, specifically COPS, with comic actors playing the police officers. Most of the material is improvised, using a broad outline, and with minimal scripted material. The series spawned a film, Reno 911!: Miami, featuring the same cast.

On August 13, 2009, Thomas Lennon announced through Twitter that the show had ended its six-year run.

The show is a satire of the Fox Television show COPS, which follows actual police officers through their daily duties (often chasing criminals and intervening in domestic disputes). Reno 911! features members of a fictitious, inept Reno Sheriff's Department, distinct from the actual Reno Police Department and Washoe County Sheriff's Office, both of which are absent in the show. In the course of their duties patrolling both Reno and the rest of the county, the deputies sometimes address the camera directly as though being interviewed. The show deals heavily in politically incorrect and "racy" humor, including many jokes about race, sexual orientation, drug and alcohol abuse, and rape. Another main comedic aspect of the show is the incompetence of the officers, which often results in their being outsmarted by the very criminals they are attempting to control.
