Denis Dighton (1792 - August 8, 1827) was an English painter who studied at the Royal Academy. His father was caricaturist Robert Dighton, and he was married to the still-life painter Phoebe Earl. He received a commission in the army at the age of 17 through the influence of the Prince of Wales. Denis Dighton is mostly known for his paintings of the Peninsular War, the Battle of Waterloo, and the Battle of Trafalgar.
His painting "The Fall of Nelson, Battle of Trafalgar, 21 October 1805" (c. 1825) was used as the cover artwork the game Trafalgar by Warp Spawn Games.
