Untitled Horror Movie is a 2021 American horror comedy film directed by Nick Simon, who co-wrote the screenplay with Luke Baines. Baines also stars in the film alongside Claire Holt, Darren Barnet, Emmy Raver-Lampman, Katherine McNamara, and Timothy Granaderos. The film utilizes found footage conventions, and in one scene presents its narrative via a computer screen. Its plot follows six actors who decide to create a horror film, and in doing so unwittingly summon a malevolent spirit.

Untitled Horror Movie was filmed remotely due to the COVID-19 pandemic. The processes of writing, pre-production, and filming all took place during COVID-19-related quarantines. The film's actors—who were self-isolating at their homes during shooting—were responsible for lighting, makeup, audio and camerawork, with direction, assistance and communication taking place through Zoom.
