The Adouma (Aduma or Duma) are an ethnic group of Gabon, in western Africa. They primarily live on the south bank of the upper Ogooue River, in the vicinity of Lastoursville (originally an Adouma village), and are known as expert canoeists or the boatmen.
Their traditions hold that they arrived from the east or southeast, coming down the Sebe River to the Ogowe, and thence to the Doume rapids. They made canoes of Okoume, and sold slaves to the Okande, receiving European products such as guns and cloth in exchange. The Societe de Haut-Ogooue (SHO) established a post at Lastoursville and engaged the Adouma in trade for rubber, ivory and ebony.
During the 1970’s and 1980’s, many Adouma moved down the Ogowe, towards Port-Gentil.
