The
River Don (also called
Dun in some stretches) is a river in
South Yorkshire, England. It rises in the
Pennines and flows for eastwards, through the Don Valley, via
Penistone,
Sheffield,
Rotherham,
Mexborough,
Conisbrough,
Doncaster and
Stainforth. It originally joined the
Trent, but was re-engineered by
Cornelius Vermuyden as the
Dutch River in the 1620s, and now joins the
River Ouse at
Goole in the
East Riding of Yorkshire.
Don Valley is the local UK parliamentary constituency near the Doncaster stretch of the river.
