The River Rother, a waterway in the northern midlands of England, gives its name to the town of Rotherham and to the Rother Valley parliamentary constituency. It rises near Clay Cross in Derbyshire and flows in a generally northwards direction through the centre of Chesterfield, where it feeds the Chesterfield Canal, and on through the Rother Valley Country Park and several districts of Sheffield before joining the River Don at Rotherham in Yorkshire.
