The River Mease is a lowland clay river in the Midlands area of England. It flows through the counties of Leicestershire, Derbyshire and Staffordshire and forms the administrative border between these counties for parts of its length.

The river and the lower part of one of its tributaries, the Gilwiskaw Brook (pronounced jill-a-whiskey) are both protected as "one of the best examples of an unspoilt meandering lowland river". The river receives protection under European Union law as a Special Area of Conservation (SAC), and protection under UK law as a Site of Special Scientific Interest (SSSI).
