Purple Noon (French: Plein soleil; Italian: Delitto in pieno sole; also known as Full Sun, Blazing Sun, Lust for Evil, and Talented Mr. Ripley) is a 1960 crime thriller film starring Alain Delon (in his first major role), alongside Marie Laforêt and Maurice Ronet; Romy Schneider, Delon's girlfriend at the time, makes a brief cameo appearance in the film. The film follows Tom Ripley, a young American sent to Italy to convince wealthy playboy Philippe Greenleaf to return home. As Tom becomes obsessed with Philippe's luxurious lifestyle, he devises a plan that will allow him to take over Philippe's life.

Directed by René Clément, the French/Italian international co-production is loosely based on the 1955 novel The Talented Mr. Ripley by Patricia Highsmith. Anthony Minghella's 1999 film The Talented Mr. Ripley and the 2024 streaming television series Ripley are adaptations of the same source novel. The majority of the film's dialogue is spoken in French, although there are brief sequences in Italian and English.
