Luca Barbareschi (born 28 July 1956 in Montevideo) is an Italian-Uruguayan actor, television presenter, and former member of the Italian Chamber of Deputies. Barbareschi is Jewish.

He was one of four actors whom the Italian police believed had been murdered in the making of the 1980 horror film Cannibal Holocaust, where he also abused and killed a young piglet. So realistic was the film that shortly after it was released its director Ruggero Deodato was arrested on suspicions of murder. The actors had signed contracts to stay out of the media for a year in order to fuel rumours that the film was a snuff movie. The court was only convinced that they were alive when the contracts were cancelled and the actors appeared on a television show as proof.
