The Lomami River is a major tributary of the Congo River in the Democratic Republic of the Congo. The river is approximately 1,280 kilometres (800 mi) long. It flows north, west of and parallel to the upper Congo.
Henry Morton Stanley reached the confluence of the two rivers on 6 Jan. 1877, "the affluent Lumami, which Livingstone calls 'Young's river,' entered the great stream, by a mouth 600 yards wide, between low banks densely covered with trees.":Vol.Two,176
In October 1889 M. Janssen, Governor-General of the Congo State, explored the Lomani river upstream from Isangi on the Ville de Bruxelles. After steaming for 116 hours he was stopped by rapids at a latitude of 4°27'2" S.
