Star Trek: The Animated Series (originally known simply as Star Trek but also known as The Animated Adventures of Gene Roddenberry’s Star Trek) is a 1973 animated, science fiction television series set in the Star Trek universe following the events of Star Trek: The Original Series of the 1960s. The animated series was aired under the name Star Trek, but it has become widely known under this longer name (or abbreviated as ST: TAS or TAS) to differentiate it from the original live-action Star Trek. The success of the original live action series in syndication, and fan pressure for a Star Trek revival, led to The Animated Series from 1973–1974, as the source of new adventures of the Enterprise crew, the next being the 1979 live-action feature film Star Trek: The Motion Picture.

These books are novelizations of the stories from the television series.
