West Duddon Offshore Wind Farm or West of Duddon Sands wind farm (WoDS) is a proposed offshore wind farm to be located 14km south west of Walney Island off the coast of Cumbria, in the Irish Sea, England. It is being developed by Morecombe Wind Ltd, a partnership between Scottish Power, Dong Energy and Eurus Energy. The farm gets its name from a large sand bank uncovered at low water in the mouth of the estuary of the River Duddon to the north of the Barrow-in-Furness Peninsula. The farm is somewhat to the south west of the Sands and will cover an area of approximately 66 sq km.

In 2004 Morecombe Wind was awarded a 50 year lease from The Crown Estate to develop a wind farm at West Duddon as part of the second UK offshore wind farm tendering process known as "Round 2".

The West Duddon Offshore Wind Farm project includes constructing the wind turbines and their foundations, building offshore substations, installing power cables both undersea and onshore, as well as an extension to the existing onshore Electrical substation to house the equipment needed for connection into the UK National Grid. This work is estimated to take about 2 years.

The West Duddon Offshore Wind Farm planning application was filed in April 2006 and consent was granted in September 2008. The application was for between 83 and 139 turbines with a nameplate capacity of 500 MW. However permission was granted for only 108 turbines due to geological siting issues. This will provide up to 389 MW of power.
