Asteroid City (styled as "Asteroid City") is a 2023 American comedy drama film written, directed, and produced by Wes Anderson, from a story he wrote with Roman Coppola. It features an ensemble cast, including Jason Schwartzman, Scarlett Johansson, Tom Hanks, Jeffrey Wright, Tilda Swinton, Bryan Cranston, Edward Norton, Adrien Brody, Liev Schreiber, Hope Davis, Steve Park, Rupert Friend, Maya Hawke, Steve Carell, Matt Dillon, Hong Chau, Willem Dafoe, Margot Robbie, Tony Revolori, Jake Ryan, and Jeff Goldblum. Its plot mostly follows a play about a Junior Stargazer convention in a retrofuturistic version of 1955, but it becomes metatextual because the making of the play is the subject of a television documentary. The story is about extraterrestrials and UFOs witnessed in the American Southwestern desert in close proximity to atomic test sites after World War II.

The project was announced in September 2020 as an untitled romance film, with Anderson writing, producing and directing, alongside Jeremy Dawson of American Empirical Pictures and Steven Rales of Indian Paintbrush. In February 2021, it was described as being about a "group of brainy teenagers". Originally set for Rome, filming took place in Chinchón, Spain, between August and October, 2021, with cinematographer Robert D. Yeoman. Several sets resembling a desert landscape and a mock train station were used. Post-production included editor Barney Pilling and a musical score composed by frequent Anderson composer Alexandre Desplat, featuring country and western songs from many artists. The official title for Asteroid City was revealed in October 2021 at the BFI London Film Festival.

Asteroid City premiered at the 76th Cannes Film Festival on May 23, 2023, where it competed for the Palme d'Or. It began a limited theatrical release through Focus Features in the United States on June 16, 2023, expanding to a wide release a week later. It grossed $54 million worldwide on a $25 million budget, and received generally positive reviews.
