TOS recurring characters
Real world article
(written from a production point of view)
This page is a list of characters who appear in multiple episodes of Star Trek: The Original Series, not including characters played by the main series cast.
Appearance counts are likely approximate. In cases where a performer played more than one character, the count applies only to the character named on the same row of the table. When there is a plus sign with a second number, the latter represents additional TOS appearances due to the use of archival footage from earlier episodes. Characters that were intended to recur in additional episode(s) – but fell victim to a script oversight, misspoken dialog, or a deleted scene – are noted with a one-half symbol (½) appended to their appearance count.
