The River Kent is a short river in the county of Cumbria in England. It originates in hills surrounding Kentmere, and flows for around 20 miles (32 km) into the north of Morecambe Bay.

The river flows in a generally north to south direction, passing through Kentmere, Staveley, Burneside, Kendal and Sedgwick.
