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 upper reaches and the western bank of the estuary are located within the boundaries of the Lake District National Park. The river flows in a generally north to south direction, passing through Kentmere, Staveley, Burneside, Kendal and Sedgwick. Near Sedgwick, the river passes through a rock gorge which produces a number of low waterfalls. This section is popular with kayakers as it offers high quality whitewater for several days after rain. The village of Arnside is situated on the east bank of the Kent estuary, just above Morecambe Bay, and a tidal bore known as the Arnside Bore forms in the estuary at this point on high spring tides.

Kentmere is a valley, village and civil parish in the Lake District National Park, a few miles from Kendal in the Westmorland and Furness district of Cumbria, England. Historically in Westmorland, at the 2011 census Kentmere had a population of 159.
