Acornhoek, commonly known as Khenhuk, is a semi-rural town situated in the north eastern areas of Bushbuckridge in the Mpumalanga province of South Africa.
Acornhoek is part of the Bushbuckridge Local Municipality under the Ehlanzeni District Municipality in Mpumalanga province.
Established in the late 1950s, the town is located about 38 km south-east of Hoedspruit in Limpopo and 165 km north-west of Komatipoort near the border post of Mozambique and eSwatini. The name Acornhoek is variously explained as being an adaptation of Eekhoornhoek (‘squirrel corner’); derived from the German surname Eichhorn, and named after the acorn-like fruits of the marula tree.
The main languages spoken in Acornhoek are Sepulana and Xitsonga. Most of Vatsonga people occupy the eastern side of this semi-rural township while the Mapulana people are settled on the western and southern areas.
