Map - Overijssel (Provincie Overijssel)

Overijssel (, ; Oaveriessel ; Oberyssel) is a province of the Netherlands located in the eastern part of the country. The province's name translates to "across the IJssel", from the perspective of the Episcopal principality of Utrecht by which it was held until 1528. The capital city of Overijssel is Zwolle (pop. 127,497 ) and the largest city is Enschede (pop. 158,986). The province had a population of 1,162,215 as of November 2019. The land mostly consists of grasslands and some forests (including Sallandse Heuvelrug National Park); it also borders a small part of the IJsselmeer to the west.

Overijssel is bordered by Germany (Lower Saxony and North Rhine-Westphalia) to the east, the Achterhoek region of Gelderland to the south, the Veluwe region of Gelderland and Flevoland to the west, and Friesland and the former moors of Drenthe to the north. Overijssel comprises three regions: Kop van Overijssel in the northwest, Salland in the centre of the province, and Twente in the east. Besides the capital Zwolle, other major cities are Almelo, Deventer, Hengelo, Enschede, and Kampen.

To the southeast, the province's surface is mostly sandy, interspersed with small rivers such as the Regge and Dinkel and other brooks. In the northwest, the geology is dominated by sediments from the Overijsselse Vecht and clay. The northern parts were once covered by veen (bogs) which separated the dryer and more arable south from Drenthe and which have been exploited as fuel to a large degree. Only small patches survive today (Engbertsdijksvenen near Geesteren, Witteveen (near Haaksbergen), and the Aamsveen (near Enschede). The extreme northwest is dominated by a system of lakes formed by former peat-mining and protected under the De Weerribben-Wieden National Park status, which is a valuable wetland.

The highest point in Overijssel is the summit of the Tankenberg, a hill in the municipality of Losser, at 85 metres (278 ft). The lowest point is in the Mastenbroek Polder near Kampen at 2 metres (6 ft) below sea level.
