L'Eclisse (English: "The Eclipse") is a 1962 romantic drama film co-written and directed by Michelangelo Antonioni and starring Alain Delon and Monica Vitti, with Francisco Rabal, Lilla Brignone, and Louis Seigner. Filmed on location in Rome and Verona, the story follows a young woman (Vitti) who pursues an affair with a confident young stockbroker (Delon). Antonioni attributed some of his inspiration for L'Eclisse to when he filmed a solar eclipse in Florence. The film is considered the last part of a trilogy and is preceded by L'Avventura (1960) and La Notte (1961).

L'Eclisse won the Special Jury Prize at the 1962 Cannes Film Festival and was nominated for the Palme d'Or. Described by Martin Scorsese as the boldest film in the trilogy, it is one of the director's more acclaimed works. In 2008, the film was included on the Italian Ministry of Cultural Heritage’s 100 Italian films to be saved, a list of 100 films that "have changed the collective memory of the country between 1942 and 1978."
