Derwentwater, or Derwent Water, is a lake in the Lake District in North West England, immediately south of Keswick. It is in the unitary authority of Cumberland within the ceremonial county of Cumbria. It is the third largest lake by area, after Windermere and Ullswater. It has a length of 4.6 kilometres (2.9 mi), a maximum width of 1.91 kilometres (1.19 mi), and an area of 5.4 square kilometres (2.1 sq mi). Its primary inflow and outflow is the River Derwent, which also flows through Bassenthwaite Lake before reaching the Irish Sea at Workington. There are several islands within the lake, one of which is inhabited. Derwentwater is a place of considerable scenic value. It is surrounded by hills (known locally as fells), and many of the slopes facing Derwentwater are extensively wooded. A regular passenger launch operates on the lake, taking passengers between various landing stages. There are seven lakeside marinas, the most popular stops being Keswick, Portinscale and the Lodore Falls, from which boats may be hired. Recreational walking is a major tourist activity in the area and there is an extensive network of footpaths in the hills and woods surrounding the lake.

The Keswick to Borrowdale road runs along the eastern shore of the lake and carries a regular bus service. There is a lesser, or unclassified, road along the western shore connecting the villages of Grange and Portinscale.

From 2008 to 2014, the lake was believed to be the last remaining native habitat of the vendace (Coregonus vandesius) fish from the four originally known sites: Bassenthwaite Lake and Derwentwater in the Lake District, and the Castle Loch & Mill Loch in Lochmaben. However, a breeding population was discovered at Bassenthwaite Lake by conservationists in September 2014. The lake (and many others) is polluted with the invasive New Zealand Pigmyweed.

'Derwent' is " '(River) with oak trees', traditionally explained from Brit." (i.e.: Brythonic Celtic) or Old Welsh, " 'derwā' 'oak' plus suffixes, hence of the same origin as other English rivers named Derwent, Darwen, Darent and Dart...The river gave its name to Derwent Water (which was also known as the 'Lake of Derwent', 'Keswick Lake', or 'Keswick Water' in the 18th-19th centuries)...". Plus "OE 'wæter', with the meaning probably influenced by its ON relative 'vatn'."

There are numerous islands in Derwentwater, the largest being Derwent Island, Lord's Island, St Herbert's Island, Rampsholme Island, Park Neb, Otter Island and Otterbield Island. There is a house on Derwent Island.

St. Herbert's Island is named after a 7th-century hermit priest, Herbert of Derwentwater.
