Star Trek: Section 31 is an upcoming American science fiction television film directed by Olatunde Osunsanmi and written by Craig Sweeny for the streaming service Paramount+. It is intended to be the first television film in the Star Trek franchise and part of executive producer Alex Kurtzman's expanded Star Trek Universe. A spin-off from the series Star Trek: Discovery, the film is set in the franchise's "lost era" between the Star Trek: The Original Series films and the series Star Trek: The Next Generation. It follows Philippa Georgiou as she works with Section 31, a secret division of Starfleet tasked with protecting the United Federation of Planets, and must face the sins of her past.

Michelle Yeoh stars as Georgiou, reprising her role from Discovery. Development on a spin-off television series with Yeoh was confirmed in January 2019, but filming was delayed by the COVID-19 pandemic. A different Discovery spin-off series, Star Trek: Strange New Worlds, was then prioritized. Section 31 was redeveloped into a film, which was announced in April 2023. Omari Hardwick, Kacey Rohl, Sam Richardson, Sven Ruygrok, Robert Kazinsky, Humberly Gonzalez, and James Hiroyuki Liao also star in the film, which is produced by CBS Studios in association with Secret Hideout and Roddenberry Entertainment. Filming took place in Toronto, Canada, from January to March 2024.

Star Trek: Section 31 is scheduled to be released on the streaming service Paramount+ on January 24, 2025.
