Maria Luisa Mangini (2 February 1928 – 15 February 2011), better known as Dorian Gray, was an Italian actress.

Gray made her stage debut in 1950. After five years she left the theater world and devoted herself to the cinema.

The role she played most often in films was that of a seductive sex kitten. She played the titular "bad girl" in Totò, Peppino e la malafemmina. She also appeared in Michelangelo Antonioni's Il grido. In 1957, she took part in The Nights of Cabiria by Federico Fellini.

On February 15, 2011, Gray committed suicide by gunshot at her home in Torcegno. She was 83 years old; however, some media reported her age as 75, since she claimed to have been born in 1936.
