Paper Heart is a 2009 American romantic comedy film starring Charlyne Yi and Michael Cera as fictionalized versions of themselves based on their rumored relationship, though Yi has said they never dated.

The plot for the film is based on Charlyne Yi's original idea of a documentary, which director Nick Jasenovec suggested would be accentuated with a fictional storyline. The film premiered at the 2009 Sundance Film Festival, where it won the Waldo Salt Screenwriting Award.
