Triton Knoll Wind Farm is a proposed offshore wind farm 33km off the coast of Lincolnshire, in the North Sea, England. It is being developed by Npower Renewables. If completed the farm will be the largest offshore farm in the world, consisting of 240 turbines with a nameplate capacity of 1200 MW.

In 2003 The Crown Estate and the Government opened a second tender round for offshore wind farm development sites within three selected 'Strategic Areas' around the coast of Great Britain. As a result of the Round 2 tender process, RWE npower renewables was awarded the development rights to take forward a 1,200 megawatt (MW) offshore wind farm called Triton Knoll.

Triton Knoll Offshore Wind Farm is within the Greater Wash Strategic Area and is located off the east coast of England, approximately 33 kilometres off the coast of Lincolnshire and 46km from the coast of North Norfolk. RWE npower renewables is now progressing the development of the offshore wind farm and is carrying out an Environmental Impact Assessment (EIA) of the site.
