Indian Summer (Italian: La prima notte di quiete) is a 1972 Italian romantic drama film directed by Valerio Zurlini and starring Alain Delon, Sonia Petrovna, Renato Salvatori, Alida Valli, Adalberto Maria Merli, Salvo Randone and Lea Massari. The version released in France and West Germany runs less than the Italian cut.

The film tells the story of a gifted but restless young man who cannot live up to the high traditions of his family and survives in obscurity, taking casual teaching jobs and living in a loveless partnership with a depressed woman. His aimless existence reaches a crisis point when he falls for one of his pupils, a beautiful but badly damaged girl.

Despite the film receiving positive reviews from critics, it was a commercial failure.
