The Lighthouse is a 2019 psychological horror film directed and produced by Robert Eggers, who co-wrote the screenplay with his brother Max Eggers. Shot in black-and-white with a 1.19:1 aspect ratio, the film stars Willem Dafoe and Robert Pattinson as two lighthouse keepers who start to lose their sanity when a storm strands them on the remote island where they are stationed.

According to Eggers, although the final story bears little resemblance to Edgar Allan Poe's fragment "The Light-House", the film began as an attempt by his brother Max Eggers to do a contemporary take on the Poe story. When the project stalled, Robert offered to work with his brother and the project evolved into a period thriller with the Poe elements removed.

Dafoe and Pattinson were cast as the lead characters in February 2018. Principal photography began on April 9, 2018, and lasted a total of 34 days in Leif Erikson Park in Cape Forchu, Nova Scotia, Canada, and inside a hangar at Yarmouth International Airport in Yarmouth, Nova Scotia.

The film had its world premiere at the 72nd Cannes Film Festival on May 19, and was theatrically released on October 18, 2019, by A24. The film received universal acclaim, with critics highlighting the technical aspects (notably the cinematography and production design), Eggers' screenplay and direction, and the performances of the leads. The film is nominated for Best Cinematography at the 92nd Academy Awards.
