Sappora VII was the seventh planet in the Sappora planetary system, known for its richness in pergium. In the 24th century, Sappora VII was under the jurisdiction of New Sydney, an independent planet heavily influenced by the Orion Syndicate. It was home to the Tigan family and their mining business.

Lieutenant junior grade Ezri Dax, née Tigan, traveled to Sappora VII to use her mother Yanas Tigan's influence with the New Sydney police bureau to help locate Chief Miles O'Brien, who went missing on New Sydney in 2375. (DS9: "Prodigal Daughter")

"Prodigal Daughter" only referred to New Sydney in the Sappora system in dialogue, though as a location different from the Tigan family home once the main characters get there. The planet was twice mentioned in script notes as Sappora VII.
The Star Trek Encyclopedia (4th ed., vol. 2, p. 250) also treated Sappora VII as a different planet than New Sydney.
