Zenopolis (Ancient Greek: Ζηνούπολις) was an ancient Roman and Byzantine city in Isauria. Its site is located near Elmayurdu in Asiatic Turkey.

This city was the birthplace of Emperor Zeno (474–491), and was renamed in his honour. Its previous name was Rusumblada, according to Ramsay, but the author of the entry on Rusumblada in Paulys Real-Encyclopaedie der classischen Altertumswissenschaft considers this uncertain. Its modern name is Isnebol. George of Cyprus mentioned it in the 7th century, as did Constantine Porphyrogenitus in the 10th century, as a city of the Isaurian Decapolis.

The city is recorded as a bishopric in the 6th-century Notitia Episcopatuum of the Patriarchate of Antioch, but in about 732 Isauria was attached to the Patriarchate of Constantinople.
