A Lizard in a Woman's Skin (Italian: Una lucertola con la pelle di donna) is a 1971 giallo film co-written and directed by Lucio Fulci and produced by Edmondo Amati and Robert Dorfmann.

It stars Florinda Bolkan, Stanley Baker, Jean Sorel, Alberto de Mendoza, Silvia Monti, Anita Strindberg, Mike Kennedy, George Rigaud and Leo Genn.

Set in London, the film follows Carol Hammond (Bolkan), the daughter of a respected politician, who experiences a series of vivid, psychedelic nightmares consisting of debauched sex orgies and LSD use.

Carol has been visiting a psychoanalyst, Dr. Kerr, because she has been experiencing disturbing dreams involving her libertine next-door neighbour, Julia Durer, who often hosts raucous, drug-fueled parties in her apartment.

In the dreams, Carol, wearing a fur coat, makes her way through a long hallway filled with naked people, before engaging in sexual activities with Julia.

After Julia threatened to expose their lesbian affair, Carol killed her that night and fabricated her nightmares to Dr. Kerr in a bid to plead temporary insanity.

The scene was so graphic and realistic that several crew members were forced to testify in court to disprove the accusation that real dogs were used in the film.

[5] Carlo Rambaldi, a special effects artist, saved Fulci from a two-year prison sentence by presenting the fake dog props in court to a seemingly unconvinced judiciary.

Donald Guarisco of AllMovie described the film as "a wild ride that offers plenty of bizarre moments that will stay stuck in the viewer's mind.
