Goodbye First Love (French: Un amour de jeunesse) is a 2011 romantic drama film written and directed by Mia Hansen-Løve.

During her studies, she gradually falls in love with her much older professor Lorenz, in whom she sees a stable and secure influence and intellectual match.

Four more years pass, and Camille, now with a career and a relationship with Lorenz, encounters Sullivan's mother by chance and reconnects with her old boyfriend.

She brings the hat that Sullivan had bought her for their own getaway years before, but unbeknownst to her as she plays in the river, it blows into the water and floats away as the film ends.

The website's critics consensus reads, "Goodbye First Love captures teen ardor with a patiently naturalistic approach, further proving writer-director Mia Hansen-Løve is a major talent to watch.

Club said that "Goodbye First Love sometimes tells when it should show, and in their younger guises, particularly, Créton and Urzendowsky come off as so self-absorbed that they're almost insufferable".
