The Adouma (or Duma) are an ethnic group of Gabon, in central Africa.
[1] They primarily live on the South bank of the upper Ogooué River, in the vicinity of Lastoursville (originally an Adouma village), and are known as expert canoeists or the boatmen.
[2] Their traditions hold that they arrived from the East or Southeast, coming down the Sebe River to the Ogowe, and thence to the Doumé rapids.
[3] They made canoes of Aucoumea wood, and sold slaves to the Okandé, receiving European products such as guns and cloth in exchange.
The Société du Haut-Ogooué (SHO) established a post at Lastoursville and engaged the Adouma in trade for rubber, ivory, and ebony [citation needed].
