Flesh for Frankenstein is a 1973 horror film written and directed by Paul Morrissey. It stars Udo Kier, Joe Dallesandro, Monique van Vooren and Arno Juerging. Interiors were filmed at Cinecittà in Rome by a crew of Italian filmmakers. In West Germany and the United States, the film was released as Andy Warhol's Frankenstein (though only the title Frankenstein appeared on the print itself) and was presented in the Space-Vision 3D process in premiere engagements.

It was rated X by the MPAA due to its explicit sexuality, nudity and violence. In the 1970s, a 3-D version played in London and Stockholm. A 3-D version also played in Australia in 1986, along with Blood for Dracula. The gruesomeness of the action was intensified in the original release by the use of 3D. In 1973 Paul Morrissey and Joe Dallesandro came to Italy to shoot a film for producers Andrew Braunsberg and Carlo Ponti. The original idea came from director Roman Polanski, who had met Morrissey when promoting his film What?, with Morrissey stating that Polanski felt he would be "a natural person to make a 3-D film about Frankenstein. I thought it was the most absurd option I could imagine." Morrissey convinced Ponti to not just make one film during this period, but two, which led to the production of both Flesh for Frankenstein and Blood for Dracula.

The staff included many Italians in the production, including Enrico Job as the production designer, pianist Claudio Gizzi for the score and special effects artist Carlo Rambaldi for the special effects. Warhol's contributions to the film were minimal, including visiting the set once and briefly visiting during the editing period.At first, Morrissey intended to rely on improvisation for the dialogue for his characters, but had to come up with a new method, as this would not work for some actors, such as Udo Kier. This led to Morrissey preparing the dialogue day-by-day, dictating it to Pat Hackett at his studio.

Filming began on Flesh for Frankenstein on March 20th, 1973. Flesh for Frankenstein was shown in West Germany on 30 November 1973 as Andy Warhol's Frankenstein. It was later shown on April 2nd, 1974 at Filmex, the Los Angeles International Film Exposition. The film was submitted to Italian censors in January 1974 under the title Carne per Frankenstein, which was initially different from the American edit, containing some less explicit sex scenes and more violent death scenes. That version was initially banned in Italy, but an edited version was resubmitted under the title Il mostro è in tavola, barone... Frankenstein, with changes to dialogue as well as the addition and removal of various scenes, giving it an 89-minute running time for distribution by Gold Film.

Ian Jane of DVD Talk said of the film, "Flesh for Frankenstein is a morbid and grotesque comedy that won't be to everyone's taste but that does deliver some interesting humor and horror in that oddball way that Morrissey has."Bruce G. Hallenbeck commented in his book, Comedy-Horror Films: A Chronological History, 1914-2008, that Flesh for Frankenstein is perverse and distasteful, but in a way which is deliberately parodical and even a political statement. He remarked, "The irony inherent in the screenplay by Morrissey and Tonino Guerra ... gives the film a winking detachment, so that you find yourself convulsed with laughter during some of the goriest scenes ever filmed."

As of January 2018, the film held a 92% 'fresh' rating on movie review aggregator website Rotten Tomatoes. In 2012, Time Out polled authors, directors, actors and critics who had worked in the horror genre on their top horror films, with Flesh for Frankenstein placing at number 98 on the top 100.
