The goat locker was a starship/starbase section in several cultures. In Ancient Earth wet navies, the goat locker was an area reserved for the chief petty officers that even their commanding officer had to request permission to get in that room.

In one particular instance (Deep Space L-9), the goat locker was the computer control room that contained all the vital records of the facility. (RIS Bouteina: "Two-Speed Intellect")
