Alien: Romulus is a 2024 science fiction horror film directed by Fede Álvarez and produced by Scott Free Productions and 20th Century Studios, serving as a standalone entry in the Alien franchise set between the events of Ridley Scott's original Alien (1979) and James Cameron's Aliens (1986). The film follows a group of young space colonists who board an abandoned deep-space station and unwittingly encounter the most terrifying life form in the galaxy. Álvarez, whose previous work includes the Evil Dead remake and Don't Breathe, brings his distinctive talent for sustained dread and practical horror craft to the franchise's mythology.

The film stars Cailee Spaeny as Rain Carradine, a colonist desperate to escape her dead-end mining world who leads a small crew onto the derelict station Romulus in search of equipment that could fund their escape to a better planet. David Jonsson plays her android companion Andy, whose shifting allegiances become one of the film's central sources of tension. Archie Renaux, Isabela Merced, Spike Fearn, and Aileen Wu round out the crew. The film generated significant discussion for its use of digitally recreated imagery of the late Ian Holm, who played the android Ash in the original 1979 film.

Alien: Romulus earned strong critical reception and proved a considerable commercial success, grossing over $350 million worldwide against a reported budget in the range of $80 million — making it one of the most profitable entries in the Alien franchise in decades. Critics praised Álvarez's disciplined command of suspense, the film's impressive practical effects work, and its skill in expanding the franchise's mythology while delivering the sustained terror that the series' best installments have always provided. The film was seen as a significant course correction for a franchise that had struggled with its two most recent installments.
