A crossover is an event in a television franchise where characters from one series appear with the main characters and settings from another series. Many Star Trek crossovers served as introductions to the cast and setting of the latest show, while others were nostalgic reminiscences of previous series.

The following is a list of crossover characters who appeared first in one television or film series, and subsequently appeared in a different television or film series.

Characters are listed under the series in which they first appeared. Appearances by regular cast characters are not listed for the series in which they were regular cast.

Also note that a number of those listed below may not have necessarily had interactions with characters from the latter series, nor be live (vs. hologram, hallucination, etc.) versions of their former selves.
