Garfield County is located in the Southeast corner of Washington State, bordered on the north by the Snake River and on the South by the Blue Mountains, between Columbia and Asotin Counties.

The county supports one port district, the Port of Garfield, and is serviced by overland transportation along US Highway 12, with connections to major interstates.
