Preaching to the Perverted is a 1997 British sex comedy-drama film written and directed by Stuart Urban.

The film features Guinevere Turner in her first starring role as Tanya Cheex, a New York dominatrix. Tom Bell plays Henry Harding MP and Christien Anholt plays Peter Emery. In addition, several well-known BDSM performance artists appear, including Chaos Clowns, Luci the Axle Grinder, also known as "Lucifire", Miss Kimberly, The Fetish Nun, Suzi Woodroffe, and Tutu.

The film was originally developed by the BBC, but they later dropped the script, believing it would never be suitable for broadcast on UK TV. However, in April 2004, the film was shown on terrestrial TV in the United Kingdom on BBC One.

The film was banned in the Republic of Ireland by then-film censor Sheamus Smith on 28 October 1997; he also banned the subsequent video release of the film. The trailer caused a mass recall of the rental VHS release of Donnie Brasco (which had been passed as an 18), because the trailer had not been classified. 3,300 copies of that cassette were withdrawn and replaced, with a potential fine of €1000 to stores providing it. A 2003 video release in the United States was cut in order to receive an age rating.

In 2013, the film became the first European feature film to be restored and remastered on crowd-funding site Kickstarter by its fans. The remastered Blu-ray became available in August 2013.
