The Požega Valley (Croatian: Požeška kotlina) is a geographic microregion of Croatia, located in central Slavonia, encompassing the eastern part of the Požega-Slavonia County. It is located in the Pannonian Basin, bounded by Psunj, Papuk and Krndija mountains from west and north, and Požeška Gora and Dilj from south and east, as the Pannonian plain is interspersed by horst and graben structures. The largest settlement in the region is the city of Požega, followed by Pleternica and Kutjevo. The main watercourse in the region is Orljava River. The region covers 1,249 square kilometres (482 square miles) and has a population of 60,599.
The Požega Valley was first inhabited in the prehistoric era, with archaeological finds spanning the Neolithic to classical antiquity and the Early Middle Ages, the period to which the oldest surviving historical records of the region date. Between the 13th and the 16th centuries, the region was organized as the centre of the Požega County and a royal estate. Ottoman rule in the region lasted for about 150 years—from the 1530s to the 1680s. During that time, the area was the centre of Sanjak of Pojega. Subsequently, the city of Osijek became the administrative and military centre of the newly formed Kingdom of Slavonia from Požega.
