The Sappora system was a independent planetary system located outside of Federation space, near the Timor system.

In 2375, the primary inhabited planet in the system was New Sydney, with the rest of the planets in the system falling under the jurisdiction of the New Sydney Police. The Tigan family, under Yanas Tigan, owned the sixth-largest pergium mining operation in the sector located on the planet Sappora VII.

Ezri Dax, née Tigan, traveled home to the system in 2375 to enlist her mother's help in searching for Miles O'Brien, who had gone missing on New Sydney. (DS9: "Prodigal Daughter")
