Portrait of Mary Nisbet is an 1803 portrait painting by the French artist François Gérard depicting Mary Nisbet, then Countess of Elgin.

[1] [2] [3] It was likely painted in Paris after her husband Lord Elgin had been detained by the French authorities following the collapse of the Peace of Amiens and the outbreak of the Napoleonic Wars.

She interceded on her husband's behalf with Napoleon, securing his eventual release under parole.

[4] She had previously accompanied him during his spell as British Ambassador to the Ottoman Empire when he had acquired the Elgin Marbles.

Today it is in the collection of the Scottish National Gallery in Edinburgh, having been acquired in 1921.
