The Orias system was a star system in Cardassian space in the late 24th century. It has at least three planets, including Orias III.

In 2371, Starfleet Intelligence suspected a fleet of Cardassian vessels was secretly being built in the system. The Maquis feared this might be a build up to new attacks by the Cardassians so Thomas Riker stole the USS Defiant from Deep Space 9 to investigate. He was prevented from entering the system by a group of Keldon-class vessels. (DS9 episode: "Defiant")

Starfleet’s suspicions turned out to be accurate when it was later revealed a secret fleet was being built in the system by the Obsidian Order in a joint operation with the Tal Shiar to destroy the Founders homeworld in the Gamma Quadrant. (DS9 episode: "Improbable Cause", DS9 novel: Rising Son)

After the Dominion War, the system became a protectorate of the Romulan Star Empire. Ethan Locken planned to attack the system with a missile loaded with deadly prion viruses. (DS9 - Section 31 novel: Abyss)

Earlier that year, Kasidy Yates conducted a cargo run to the Orias system where she obtained a shipment of Rakalian p'losie. (DS9 - Avatar novel: Book One)
