The River Derwent is a river in the Lake District in Cumbria in north-west England. The name Derwent is derived from the Celtic word for oak .

The Derwent arises above the hamlet of Seathwaite west of the Glaramara from the confluence of the Styhead Gill and Grains Gill , then flows north through the Borrowdale valley and flows into the lake Derwentwater , which it gives its name. The river leaves the lake near the village of Keswick , where the River Greta flows into it; it then flows into Bassenthwaite Lake . At Cockermouth , the River Cocker flows into the Derwent. Behind Cockermouth, the Derwent flows north past the place Papcastle , where a Roman camp was named after him. The Derwent flows into the Irish Sea at Workington .

The Bowder Stone is a large boulder near Grange in Borrowdale. His name probably comes from Balder , Odin's son from the Nordic world of gods. In 2015 the terrain near the river on the Derwent river was flooded.
