Star Trek: Nemesis is a 2002 American science fiction film directed by Stuart Baird. It is the tenth film in the Star Trek franchise, as well as the fourth and final film to star the cast of Star Trek: The Next Generation. It was written by John Logan from a story developed by Logan, Brent Spiner, and producer Rick Berman. In the film, which is set in the 24th century, the crew of the USS Enterprise-E are forced to deal with a threat to the United Federation of Planets from a clone of Captain Picard named Shinzon, who has taken control of the Romulan Star Empire in a coup d'état.

Principal photography for the film took place from November 2001 to March 2002. Nemesis held its world premiere at Grauman's Chinese Theatre in Los Angeles on December 9, 2002.

The film was released in North America on December 13, 2002 by Paramount Pictures, and received generally negative reviews, with publications considering it to be the worst in the franchise. The film was a box office failure, earning $67 million worldwide against a $60 million budget. Plans for a final film featuring The Next Generation cast were scrapped, and the film series was rebooted instead with Star Trek in 2009, which was a box office success. The television series Star Trek: Picard, a continuation of The Next Generation and Nemesis set two decades after the latter at the end of the 24th century, premiered in 2020.
