Star Trek is an American science fiction entertainment franchise. The original Star Trek is an American television series, created by Gene Roddenberry, and followed the interstellar adventures of Captain James T. Kirk and the crew of an exploration vessel of a 22nd century galactic "United Federation of Planets" - the Starship Enterprise. This series debuted in 1966 and ran for three seasons, after an initial pilot film “The Cage” with a mostly different cast was rejected by Paramount, though this pilot is now routinely packaged with the original series. Following the release of other series in the franchise, the Kirk-lead series was retroactively referred to as "Star Trek: The Original Series". These adventures were continued by the short-lived Star Trek: The Animated Series and six feature films. Four more television series were eventually produced, based in the same universe but following other characters:Star Trek: The Next Generation, following the crew of a new Starship Enterprise set a century after the original series; Star Trek: Deep Space Nine and Star Trek: Voyager, set contemporaneously with The Next Generation; and Star Trek: Enterprise, set before the original series, in the early days of human interstellar travel. Four additional feature films were produced, following the crew of The Next Generation, and most recently a 2009 movie reboot of the franchise featuring a young crew of the original Enterprise set in an alternate timeline.

The franchise also includes dozens of computer and video games, hundreds of novels, as well as a themed attraction in Las Vegas (opened in 1998 and closed in September 2008), and at least two traveling museum exhibits of props. Beginning with the original television series and continuing with the subsequent films and series, the franchise has created a cult phenomenon and has spawned many pop culture references.

The core of the Star Trek franchise is six television series: The Original Series, The Animated Series, The Next Generation, Deep Space Nine, Voyager, andEnterprise. In total 726 Star Trek episodes have been produced across the 30 seasons of the TV series.
