Obselidia is a 2010 American road drama film written and directed by Diane Bell in her directorial debut. It stars Michael Piccirilli, Gaynor Howe, and Frank Hoyt Taylor. It tells the story of a lonely librarian who believes love is obsolete until a road trip to Death Valley with a beguiling cinema projectionist teaches him otherwise.

The film had its world premiere at the Sundance Film Festival on January 22, 2010, where it was awarded the Alfred P. Sloan Prize and the Excellence in Cinematography Award. It was then self-distributed, and received positive reviews from critics. At the 26th Independent Spirit Awards, it was nominated for Best First Screenplay (for Bell) and the John Cassavetes Award.
