Dewmaine was an unincorporated African-American coal-mining community in Williamson County, Illinois.

Today the area is almost completely non-residential and vacant land, though it now sits at the northern edge of Carterville.

The African-American miners were allowed to keep their jobs on the provision that they joined the union.

[12] In addition to African-Americans, the mine was worked by numerous European immigrants including Polish, Russians, Czechoslovakians, and Rusyns.
