The Ilvian Medical Complex was a medical facility located in the Northeastern District on Bajor.

After his repatriation from Velos VII in 2369, Doctor Surmak Ren served as the chief administrator of this facility. (DS9: "Babel")

Presumably it was associated with the city of Ilvia (and if so provided the first mention of the oft-mentioned location), though this was not outright stated.
