The Portrait of the Duke of Wellington is a portrait by the English artist Thomas Lawrence of the Anglo-Irish soldier and politician the Duke of Wellington. It was begun in early 1815 following Wellington's success in the Peninsular War and shortly before his victory over Napoleon at the Battle of Waterloo and the subsequent allied occupation of France under Wellington's command.^[1] It is now in the collection of Apsley House, the Duke's London residence.^[2] Wellington is shown in military uniform displaying various honours including the Order of the Garter, the Order of the Golden Fleece and the Order of the Bath. He has been described as "impassive and aloof" in the painting.^[1] Lawrence's depiction of Wellington was used on the British Five Pound note between 1971 and 1991.

Lawrence, Britain's premier portrait painter of the era, depicted Wellington a number of times. A further painting The Duke on Horseback was commissioned from Lawrence by the British Secretary of War Lord Bathurst featuring Wellington on his horse Copenhagen, completed in 1818.^[3]
