Grand Bassa is a county in the west-central portion of the West African nation of Liberia.

Buchanan serves as the capital with the area of the county measuring 3,064 square miles (7,940 km2).

The port of Buchanan was constructed by LAMCO to serve the export of iron ore carried through the railway from Nimba.

The civil war destroyed the port, railway, and township built by LAMCO.

The once bustling port became a ghost town until the arrival of Arcelor-Mittal and the consequent prospects of employment.
