The Circassian fig is a fruit native to the same star system as the Circassian cat and the Circassian plague cat.

Crewman Kenneth Dalby of the USS Voyager once mentioned that he didn't "give a Circassian fig" on what was tactically correct when he wanted to save Crewman Gerron's life despite Tuvok's objections. (VOY: "Learning Curve")
