Isauria ( or ; ), in ancient geography, is a rugged isolated district in the interior of South Asia Minor, of very different extent at different periods, but generally covering what is now the district of Bozkır and its surroundings in the Konya Province of Turkey, or the core of the Taurus Mountains. In its coastal extension it bordered on Cilicia. It derives its name from the contentious Isaurian tribe (which was probably Luwian) and twin settlements Isaura Palaea (Ίσαυρα Παλαιά, Latin: Isaura Vetus, "Old Isaura") and Isaura Nea (Ίσαυρα Νέα, Latin: Isaura Nova, "New Isaura"). Isaurian marauders were fiercely independent mountain people who created havoc in neighboring districts under Macedonian and Roman occupations.
