The Star Trek film series is the cinematic branch of the Star Trek media franchise, which began in 1966 as a weekly television series on NBC, running for three seasons until it was canceled in 1969 because of poor ratings. Reruns of the series proved to be wildly successful in syndication during the 1970s, which persuaded the series' owner, Paramount Pictures, to expand the franchise.

Paramount originally began work on a Star Trek feature film in 1975 after lobbying by the creator of the franchise, Gene Roddenberry. The studio scrapped the project two years later in favor of creating a television series, Star Trek: Phase II, with the original cast. However, following the huge success of Star Wars and Close Encounters of the Third Kind, Paramount would change its mind again, halting production on the television series and adapting its pilot episode into the 1979 Star Trek feature film, Star Trek: The Motion Picture. Five more films featuring the entire original cast followed. The cast of the 1987–1994 spin-off series Star Trek: The Next Generation starred in a further four films. A reboot to the original television series, simply titled Star Trek, was released in May 2009.

Star Trek is a 2009 American science fiction film directed by J. J. Abrams, written by Roberto Orci and Alex Kurtzman and distributed by Paramount Pictures. It is the eleventh film based on the Star Trek franchise and features the main characters of the original Star Trek television series, portrayed by a new cast. The film follows James T. Kirk (Chris Pine) and Spock (Zachary Quinto) aboard the USS Enterprise as they combat Nero (Eric Bana), a Romulan from their future who threatens the United Federation of Planets. The story takes place in an alternate reality due to time travel by both Nero and the original Spock (Leonard Nimoy). The alternate timeline was created in an effort to free the film and the franchise from established continuity constraints while simultaneously preserving original story elements.

Development for Star Trek originated in 1968, when creator Gene Roddenberry announced plans to produce a prequel modeled after the television series. The concept resurfaced temporarily in the late 1980s, when it was postulated by Harve Bennett as a possible plotline for the movie that would become Star Trek VI: The Undiscovered Country, but was rejected in lieu of other projects by Roddenberry. Following the critical and commercial failure of Star Trek Nemesis and the cancellation of the television series Star Trek: Enterprise, franchise executive producer Rick Berman and screenwriter Erik Jendresen wrote an unproduced film, titled Star Trek: The Beginning, which would take place after Enterprise. However, after the split between Viacom and CBS Corporation, former Paramount president Gail Berman convinced CBS to produce a feature film. Orci and Kurtzman, both fans of the Star Trek series, were approached to write the film and Abrams was approached to direct it. Kurtzman and Orci used inspiration from novels, graduate school dissertations, as well as the series itself.
