Argylle () is a 2024 spy action comedy film directed and produced by Matthew Vaughn, and written by Jason Fuchs. The film features an ensemble cast that includes Henry Cavill, Bryce Dallas Howard, Sam Rockwell, Bryan Cranston, Catherine O'Hara, Dua Lipa, Ariana DeBose, John Cena, and Samuel L. Jackson. Its plot centers on a reclusive author who is drawn into the world of spies and espionage after she realizes that a new spy novel she is writing mirrors real-world events.

Argylle was filmed in Europe from August to December 2021. The film premiered at Odeon Luxe Leicester Square in London on January 24, 2024, before it was released by Universal Pictures and Apple Original Films in the United Kingdom on February 1, 2024, and in the United States the following day on February 2, 2024. The film received mostly negative reviews from critics and performed poorly at the box office, grossing $96.2 million worldwide against a $200 million budget. Argylle is a standalone spin-off from the Kingsman franchise, with a crossover between the two planned as part of an intended spy-focused shared universe from Vaughn.
