Bandjoun (La 'Djo in local language) is a town and commune in the Koung-Khi Department in the West Region of Cameroon. Bandjoun is also the capital of the Koung-Khi department and one of the largest traditional chefferie (chiefdom) in Bamiléké country. The chief dwells in Hialah, and has many wives.

Its inhabitants speak Ghomala' or Bandjoun which is one of the Bamiléké family of languages.

Bandjoun is located some 10 km south of Bafoussam and some 230 km north-east of Douala. Access to the municipality is by the N4 road from Bafoussam, which passes through the municipality and then goes south-east to Bayangam. The N5 road branches from the N4 in the municipality and goes south-west to Batié. The Route Bangou also branches from the N4 in the municipality and goes south through the town to Bangou.

The recent history of the Bandjoun people is relatively well-known today. Recent history, however, covers only the last two centuries. Further research on the prehistory of the village Bandjoun is needed. Some existing chronologies cite the foundation of Bandjoun village in the 14th and 15th centuries under the Royal Magistracy of Notchwegom (1525 according to some sources but probably in 1570).

It is now established that King Foudoup was the first King of Baleng who reigned between 1545 and 1573. King Fodoup had difficulty in reconciling his first two sons Tchoungafo and Notchwegom about who would succeed him at his death. He openly expressed a preference for Tchoungafo to which Notchwegom took great umbrage and decided to leave the village of his father to found his own village below in the Noun Valley. Taking care to avoid irritating small chiefdoms that existed in the area, he moved to the edge of the last village where he could finally find free land. It was at the current location of Famleng.

After installing the first encampment at Bandjoun, Notchwegom quickly disappeared. His first wife, with whom he had already had a young son barely a teenager (11 years old according to some), sought the protection of his stepfather until her son, Du'gnechom, would be old enough to succeed his father. King Foudoup used this opportunity to reconcile posthumously with his son by fully supporting his wife and introducing her little son to the art of building royal power.

Du'gnechom in turn, once he was a young adult, became leader of the camp set up by his father at Famleng and quickly developed the qualities of a great hunter and leader. He then married a young woman his mother had prepared for him who quickly gave him a son who he named Notouom. Having taken steps to expand his military to develop his hegemonic pretensions, he instructed his son on his intentions and introduced him to war strategies. Du'gnechom died probably in 1589 when his son Notouom was only 19. Notouom was the first real first level king of Bandjoun and he worked to achieve his father's objectives and expand the village of Bandjoun.

King Foudoup was succeeded by his son Tchoungafo who, in turn, reigned from 1573 to 1628. Tchoungafo installed and inducted Notouom I in 1589 to the Bandjoun throne. He was assured of that office as the successor to his father who was the founder of Bandjoun.
