Giovanni "Tinto" Brass (born 26 March 1933) is an Italian film director and screenwriter. In the 1960s and 1970s, he directed many critically acclaimed avant-garde films of various genres. Today, he is mainly known for his later work in the erotic genre, with films such as Caligula, Così fan tutte (released under the English title All Ladies Do It), Paprika, Monella (Frivolous Lola) and Trasgredire.

After Salon Kitty (1976) and Caligula (1979), the style of his films gradually changed towards erotic films. Caligula was originally supposed to be a satire on power instead of an erotic film, but the producers changed and re-edited the film entirely without Brass's consent, removing many political and comical scenes, and shooting sexually explicit sequences, to make the film a pornographic drama. The director demanded that his name be stricken from the credits, and he is only credited for "Principal Photography". Despite this, the film remains his most widely viewed work (and the highest-grossing Italian film released in the United States). Other notable works of Brass's later period include The Key (1983) and Senso '45 (2002). He was making films into his seventies.
