This is a list of named rivers that flow either wholly or partially within the boundaries of the four ceremonial counties that form Yorkshire.
The Pennines in the west and south, the North York Moors in the north-east and the Yorkshire Wolds, the coastal range of hills on the east.
This represents a large drainage area that mostly flows into the Vale of York and into the North Sea via the Humber estuary.
In the table, total lengths are given in miles (mi) and kilometres (km), and elevations are in feet (ft) and metres (m).
The use of the term source in this list is taken to mean the point at which the name of the river is first used on Ordnance Survey maps.
