Baso Liben is one of the woredas in the Amhara Region of Ethiopia. A triangular-shaped district at the southernmost point of the Misraq Gojjam Zone, Baso Liben is bordered on the south by a bend of the Abay River which separates it from the Oromia Region, on the northwest by Guzamn, and on the northeast by Aneded; the Chamwaga river defines part of its western border.
