Nysa on the Maeander was an ancient city and bishopric of Asia Minor, whose remains are in the Sultanhisar district of Aydın Province of Turkey, 50 kilometres east of the Ionian city of Ephesus, and which remains a Latin Catholic titular see.
At one time it was reckoned as belonging to Caria or Lydia, but under the Roman Empire it was within the province of Asia, which had Ephesus for capital, and the bishop of Nysa was thus a suffragan of the metropolitan see of Ephesus.
Nysa was situated on the southern slope of mount Messogis, on the north of the Maeander, and about midway between Tralles and Antioch on the Maeander.
