The Sankuru River is a major river in the Democratic Republic of the Congo. Its approximate length of 1,200 km makes it the longest tributary of Kasai River.
In the upper course it is also known as Lubilash. It flows northwards and then westwards crossing through a few towns, most notably Mbuji-Mayi and Lusambo. Then it enters the Kasai River near Bena-Bendi, at 4°17′S 20°25′E / 4.283°S 20.417°E.
