The Corubal, also known as the Rio Corubal or Tomine, is a river of West Africa, that goes to Geba estuary, a part of Atlantic ocean.
It rises near Labe in the Fouta Djallon highlands of Guinea and flows generally in an east–west direction. The Bentala River is an upper tributary. It enters Guinea-Bissau on its eastern border, then meanders generally southwest, nearing the Guinea-Bissauan border, then turns northwest, passes by Xitole, then empties into the upper end of the Geba estuary, about 50 kilometres (31 mi) upstream from the city of Bissau.
