Il paese del sesso selvaggio (English: The Country of Savage Sex), also known as Man From Deep River, Deep River Savages and Sacrifice!, is a 1972 Italian cannibal exploitation film directed by Umberto Lenzi and starring Ivan Rassimov, Me Me Lai and Pratitsak Singhara. It is perhaps best known for starting the "cannibal boom" of Italian exploitation cinema during the late 1970s and early 1980s.

It is theorized that Lenzi was trying to imitate the content of notorious Mondo cinema, which had gained considerable popularity in grindhouse theaters since Gualtiero Jacopetti and Paolo Cavara had made Mondo Cane in 1962, even though this film is fictional. Like Man from Deep River, Mondo films often focus on exotic customs and locations, graphic violence, and animal cruelty.

The film and its title were mainly inspired by A Man Called Horse, which also featured a white man who is incorporated into a tribe that originally held him captive.
