The Derwent is a river in the Lake District of the county of Cumbria in the north of England. The name Derwent is derived from a Celtic word for "oak trees".

The river rises at Styhead Tarn underneath Scafell Pike and flows in a northerly direction through the valley of Borrowdale, before continuing through Derwentwater, giving the lake its name.

The Derwent then continues into Bassenthwaite Lake, picking up the waters of the River Greta just outside Keswick.

Another tributary is the River Cocker, which joins the Derwent at Cockermouth, through which the Derwent flows after exiting Bassenthwaite Lake on its now westerly course. After leaving Cockermouth, the river flows by Papcastle where a Roman fort bears the name of the river.

The river flows into the Irish Sea at Workington.
