Smile is a 2022 American psychological supernatural horror film written and directed by Parker Finn (in his feature directorial debut), based on his 2020 short film Laura Hasn't Slept. The film stars Sosie Bacon as a therapist named Rose Cotter, who, after witnessing the bizarre suicide of a patient, goes through increasingly disturbing and daunting experiences, leading her to believe what she is experiencing is supernatural. It also stars Jessie T. Usher, Kyle Gallner, Kal Penn, and Rob Morgan, as well as Caitlin Stasey playing the same character she played in the short film.

A feature adaptation of Finn's short was announced in June 2020, and the cast was added in October 2021. Principal photography began that month in New Jersey and ended in November. Originally set for release on the streaming service Paramount+, distributor Paramount Pictures opted to release the film theatrically after positive test screenings.

Smile premiered at Fantastic Fest on September 22, 2022, and was released in the United States on September 30. The film received generally positive reviews from critics and grossed $217.4 million worldwide. An untitled sequel is in production and scheduled to be released on October 18, 2024.
