Girl on the Third Floor is a 2019 American horror film directed by Travis Stevens, who co-wrote the screenplay with Paul Johnstone and Ben Parker. It stars Phil "CM Punk" Brooks as a deeply flawed man who renovates an old home for himself and his wife, and the supernatural events that ensue as they prepare to move in.

Reviewers praised Stevens' command of the horror genre as a new director, Brooks' convincing performance, and the film's "wonderful and gross" usage of practical special effects by British effects artist Daniel Martin.
