Va savoir (Who Knows?) is a 2001 French romantic comedy-drama film directed by Jacques Rivette. It stars Jeanne Balibar, Sergio Castellitto, Marianne Basler, Hélène de Fougerolles, and Catherine Rouvel. The widely distributed theatrical version is 154 minutes. It was entered into the 2001 Cannes Film Festival.

The story of the three couples in the film sometimes parallels the Pirandello play in which the two principals, Camille and Ugo, are performing each night and follows the structure of a Goldoni comedy, in which couples undergo misunderstandings and attraction for others until the final resolution. In the film's ending, the three couples waltz in a circle to the tune Senza fine (Endless), implying that the dance of young people in love will go on forever.
