Under the Silver Lake is a 2018 American surrealist neo-noir black comedy mystery film written, produced and directed by David Robert Mitchell. Set in 2011 Los Angeles, it follows a young man (Andrew Garfield) investigating the sudden disappearance of his neighbor (Riley Keough), only to stumble upon an elusive and dangerous conspiracy.

Under the Silver Lake premiered on May 15, 2018, at the 2018 Cannes Film Festival, where it competed for the Palme d'Or, before being released nationwide in France on August 8. It was theatrically released in the United States on April 19, 2019, by A24. The film polarized critics; while its originality, direction, soundtrack, cinematography, and Garfield's performance were praised, some found the screenplay confusing, too cryptic, and lacking the substance and depth the film aimed for.
