The Black Country is an area of the West Midlands county, in the United Kingdom covering most of the Metropolitan Boroughs of Dudley, Sandwell, and some minor parts of Walsall. Dudley and Tipton are generally considered to be the centre. It became industrialised during its role as one of the birth places of the Industrial Revolution across the English Midlands with coal mines, coking, iron foundries, glass factories, brickworks and steel mills, producing a high level of air pollution.

The name dates from the 1840s, and is believed to come from the soot that the heavy industries covered the area in, although the 30-foot-thick coal seam close to the surface is another possible origin.
