Sozopolis in Pisidia, which had been called Apollonia during Seleucid times, was a town in the former Roman province of Pisidia, and is not to be confused with the Thracian Sozopolis in Haemimonto in present-day Bulgaria.
Sozopolis in Pisidia must have been situated in the border region of that province, since some ancient accounts place it in Phrygia. Its site may correspond to present-day Uluborlu in Isparta Province, Turkey. Older sources put it "Souzon, south of Aglasoun".
Fragments of the Res Gestae Divi Augusti in Greek have been found in the area.
