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

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", "Basics, Part II")

One establishing shot of Hanon IV appears to show a sun that looms unusually large in its sky.
According to Star Trek: Star Charts (p. 86), this was a binary system with a F-class star and a M-class star. The Voyager was at this system on stardate 50032.
