The Valo system was an inhabited star system on the outskirts of Cardassian territory. In the mid-24th century, many Bajoran refugees fled to this system during the Occupation of Bajor. The system had three M-class planets, all containing Bajoran settlements. These planets were designated as Valo I, Valo II, and Valo III. There was also a Bajoran settlement on the third moon of Valo I.
