Orellius Minor is an F-type star in Sector 401, and primary of the Orellius system.

In 2370, Captain Benjamin Sisko and Chief Miles O'Brien encountered an uncharted Human colony on a planet in the system. Alixus, the leader of the colony, attempted to destroy their runabout, the USS Rio Grande, by sending it into Orellius Minor. However, the trajectory was off and the runabout was later sighted in open space by the Romulan vessel Gasko. (DS9: "Paradise")
