Red Desert (Italian: Deserto rosso) is a 1964 drama film directed by Michelangelo Antonioni and starring Monica Vitti with Richard Harris. Written by Antonioni and Tonino Guerra, it was Antonioni's first color film. The story follows a troubled woman (Vitti) living in an industrial region of Northern Italy following a recent automobile accident.

Red Desert was awarded the Golden Lion at the 25th Venice Film Festival in 1964. It has received acclaim from critics. This was the last in a series of four films he made with Vitti between 1959 and 1964, preceded by L'Avventura (1960), La Notte (1961), and L'Eclisse (1962).
