Mason County was formed in 1804 from the northwestern corner of Kanawha County. Between 1817 and 1824 the boundary demarcation between Mason and Kanawha counties was settled. Jackson took a part of Mason's lands in 1831 and another parcel was taken with the creation of Putnam County in 1848. In 1867 the boundary between Mason and Jackson was readjusted, and in 1868 Mason surrendered a small parcel of land to Cabell County.
