I.D. is a 1995 film made by BBC Films about football hooliganism, directed by Philip Davis, written by Vincent O'Connell, and starring Reece Dinsdale, Sean Pertwee and Warren Clarke. It is set in 1988 in the Shadwell area of London, England and is a story about a group of Metropolitan Police officers who are sent undercover to infiltrate a gang of dangerous football hooligans.

Although set in London, a lot of the film was filmed in South Yorkshire, in particular Rotherham and Sheffield. Millmoor stadium in Rotherham served as Shadwell Town's fictional home "The Kennel". The tagline is "When you go undercover, remember one thing... Who you are." The true events that inspired the movie are chronicled in the 2013 book Running with the Firm written by former undercover detective James Bannon. The film has a cult following. In 2016, twenty one years after the original the film was released, it received a sequel named ID2: Shadwell Army.
