Twin Peaks: The Missing Pieces is a 2014 compilation of deleted and extended scenes from Twin Peaks: Fire Walk with Me, a 1992 psychological horror film directed by David Lynch and written by Lynch and Robert Engels. The scenes were not included in the early home video releases of Fire Walk with Me and remained under lock and key for over twenty years, although their content was generally known to the public via the Fire Walk with Me script.

When filming Fire Walk with Me, Lynch shot up to five hours of material but cut the film to two hours and fourteen minutes for its theatrical release, explaining that he wanted to focus the film on the story of Laura Palmer (Sheryl Lee). The deleted scenes principally concerned the FBI's investigation into the murder of Teresa Banks (Pamela Gidley), who shared a killer with Laura, and everyday interactions with characters from seasons one and two of the Twin Peaks television series (1990–91). The Missing Pieces restores characters who were entirely cut from Fire Walk with Me, such as Josie Packard (Joan Chen), Ed Hurley (Everett McGill), and Nadine Hurley (Wendy Robie), and adds material to characters whose participation was reduced in the final edit.

Although The Missing Pieces is loosely structured as a feature-length film and has a feature-length runtime, it is not a standalone story and omits expository and storyline material from Fire Walk with Me, meaning that familiarity with the original film is essential to understanding The Missing Pieces. It has generally been released as a special feature to home video releases of Fire Walk with Me, such as CBS Home Entertainment's Twin Peaks: The Entire Mystery and Twin Peaks: From Z to A and The Criterion Collection's Fire Walk with Me re-release.
