This is a list of minor fictional characters from the science fiction television series Star Trek: Voyager. Characters here are members of the crew, or passengers, on the starship Voyager as it makes its way home through unknown space during the course of the series. The minor characters generally appear at most in several episodes (out of 172), sometimes in episodes that largely concern them. Of these characters, the only ones who joined the ship during its travels are the four alien children (Azan, Icheb, Mezoti, and Rebi) taken from a Borg cube.
Characters are ordered alphabetically by family name, and only characters who played a significant recurring role in any of the series are listed.
Ayala was played by Tarik Ergin. He appears in the background of almost every episode, more than any other "named extra". He speaks, briefly, in a handful of episodes. He is the only character other than the regulars to appear in both the pilot episode and the finale.
