Us is a 2019 psychological horror film written and directed by Jordan Peele. The film features an ensemble cast, starring Lupita Nyong'o, Winston Duke, Shahadi Wright Joseph, Evan Alex, Elisabeth Moss, and Tim Heidecker. The story follows Adelaide Wilson (Nyong'o) and her family, who are attacked by a group of menacing doppelgängers, called the "Tethered".

The project was announced in February 2018, and much of the cast joined in the following months. Peele produced the film alongside Jason Blum and Sean McKittrick, having previously collaborated on Get Out and BlacKkKlansman, as well as Ian Cooper. Filming took place in California, mostly in Los Angeles, Pasadena and Santa Cruz, from July to October 2018.

Us premiered at South by Southwest on March 8, 2019, and was theatrically released in the United States on March 22, 2019, by Universal Pictures. It was a critical and commercial success, grossing $256 million worldwide against a budget of $20 million, and received praise for Peele's screenplay and direction, Nyong'o's performance, and Michael Abels' score. Since then, it has been cited as one of the best horror films of the 21st century.
