Ngoulmakong is a village in East Cameroon, Haut-Nyong Division, Messamena Sub-Division.

The official form Ngoulmakong was given under colonial rule due to influence from Bulu.

The colloquial name Sambe, which is more usually used locally than Ngoulmakong, derives from the name of a type of tree (Sterculia subviolacea) found in the region of the Nyong River, whose hard wood was reputedly used for weapon-making.

Ngoulmakong is the seat of the chief of the Bikélé North ethnic group.

The economy is dominated by subsistence farming of food crops and cash-cropping of cocoa and coffee.
