The Achterhoek is a cultural region in the Eastern Netherlands. Its name is geographically appropriate because the area lies in the easternmost part of the province of Gelderland and therefore in the east of the Netherlands, protruding into Germany. The Achterhoek lies at the east of the IJssel and Oude IJssel rivers. On the other sides, it borders Germany to the southeast and the province of Overijssel to the northeast.

Dutch Low Saxon are the Low Saxon dialects of the Low German language that are spoken in the northeastern Netherlands and are written there with local, unstandardised orthographies based on Standard Dutch orthography.
