List of Star Trek aliens
Updated: 5/20/2026, 7:38:48 PM Wikipedia source
Star Trek is a science fiction media franchise that began with Gene Roddenberry's launch of the original Star Trek television series in 1966. Its success led to numerous films, novels, comics, and spinoff series. A major motif of the franchise involves encounters with various alien races throughout the galaxy. These fictional alien races are listed here. Notable Star Trek races include Vulcans, Klingons, and the Borg. Some aspects of these fictional races became well known in American pop culture, such as the Vulcan salute and the Borg phrase, "Resistance is futile." Star Trek aliens have been featured in Time magazine, which described how they are essential to the franchise's narrative.
