The Hanon system was an inhabited planetary system. This system was located near the Tenarus Cluster in the Delta Quadrant.

In 2372, after Seska and her Kazon forces had taken over USS Voyager, she ordered repairs to begin immediately "and then set course for the Hanon system." When Chakotay asked what was in the Hanon system, Seska simply replied "your new home."

She then left the Voyager crew on Hanon IV for several days, until Tom Paris was able to regain control of the ship and return for them. (VOY: "Basics, Part I")
