Cleon was a star system, located somewhere in the space of the galaxy's Alpha or Beta Quadrants, in proximity to the Phoenix Cluster.

History and specifics

In the year 2368, the Federation starship USS Endeavour was in this system. When the Ktarians used a game to hypnotize the crew of the Enterprise-D, the next step in their plan to take over Starfleet was to have Enterprise personnel travel to Cleon and board the Endeavour.
