Arrangement in Grey and Black No. 1, best known under its colloquial name Whistler's Mother or Portrait of Artist's Mother, is an oil painting on canvas painted by the American-born painter James McNeill Whistler in 1871. The subject of the painting is Whistler's mother, Anna McNeill Whistler. The painting is 56.81 by 63.94 inches, displayed in a frame of Whistler's own design. It is now in the Musée d'Orsay in Paris, having been bought by the French state in 1891. It is one of the most famous works by an American artist outside the United States, and has been variously described as an American icon and a Victorian Mona Lisa.
