Nysa on the Maeander (Greek: Νύσα or Νύσσα) was an ancient city and bishopric of Asia Minor, whose remains are in the Sultanhisar district of Aydın Province of Turkey, 50 kilometres (31 mi) east of the Ionian city of Ephesus, and which remains a Latin Catholic titular see.

[12][6] In Greek mythology, Dionysus, the god of wine was born or raised in Nysa or Nyssa, a name that was consequently given to many towns in all parts of the world associated with cultivation of grapes.

Hierocles classes Nysa among the sees of Asia, and its bishops are mentioned in the Councils of Ephesus and Constantinople.

[10] Nysa became a suffragan of its provincial capital's metropolitan Archdiocese of Ephesus, I the sway of the Patriarchate of Constantinople.

The well-preserved theatre, built during the Roman Imperial period, is famous for its friezes depicting the life of Dionysus, god of the grape harvest, winemaking and wine.

The bouleuterion (municipal senate), later adapted as an odeon, with 12 rows of seats, offers room for up to 600-700 people.
