A moon shuttle conductor was an individual who was in charge of a moon shuttle.

In 2266, aboard the USS Enterprise, Doctor Leonard McCoy was berated by Captain James T. Kirk for not alerting the captain on the ship's red alert status during a physical. The doctor then quipped, "What am I, a doctor or a moon shuttle conductor?" (TOS: "The Corbomite Maneuver")

In the second revised draft script of "The Corbomite Maneuver" (dated 20 May 1966), McCoy's reference was instead to "a trolley car conductor".
