Isauropolis was a Roman and Byzantine era town in southern Turkey.
Also known as Isaura Vetus, the city was in the Anatolian countryside of what was Lycaonia in today's southern Turkey and may have been the chief town of Isauria (Ἰσαυρία) district. The town was mentioned by Sozomen,Ptolemy, and Heirocles. About 450 Maximinus entered the town in his war with Zeno. Its location is not known, but suggestions include Siristat or Tris Maden, about 13 miles west of Isaura. It must have been near Isaura Palaea with which it was joined.
The city was also the site of an ancient bishopric which dates from the early Christian era. Bishops from here attended both Council of Nicea and Chalcedon. There is no mention of Isauropolis in any Notitiae episcopatuum, so Ramsay supposes that the Diocese was joined with that of Leontopolis which is mentioned in all the "Notitiae". The see was resurrected in 1925 as a titular see of the Roman Catholic Church.
