Edward Duncan RWS (21 October 1803 – 11 April 1882) was a British watercolourist known for his depictions of coastal views and shipping.

After tutelage under the Havell Brothers in London, Duncan started his own engraving studio, and primarily created print works for Fores of Piccadilly.

In 1826, a project to engrave maritime scenes, after paintings by William John Huggins (the official artist to the royal court of King William IV, and King George IV) are said to have sparked Duncan's interest in marine subjects.

The influences of both Havell and Huggins undoubtedly led to Duncan's long and successful career as one of Britain's foremost marine watercolorists.

Duncan's drawings comprise a wide range of subjects but his best known works depict coastal scenes with shipping and other marine craft.
