Bas-Uele District (French: District du Bas-Uele, Dutch: District Beneden-Uele) was a district of the Belgian Congo and the Democratic Republic of the Congo. It was formed from part of Uele District in 1912. Later it was merged back into Uele District, then split out again. There were various boundary changes. It roughly corresponded in area to the present Bas-Uélé province.
