The River Penk is a small river flowing through Staffordshire, England. Its course is mainly within South Staffordshire, and it drains most of the northern part of that district, together with some adjoining areas of Cannock Chase, Stafford, Wolverhampton, and Shropshire. It flows into the River Sow, which is a tributary of the River Trent, so its waters flow ultimately into the North Sea via the Humber Estuary.

Wolverhampton is a city and metropolitan borough in the West Midlands, England. Located 12 miles (19 km) northwest of Birmingham, the population in 2021 was 263,700.
