Marie-Élisabeth Gabiou, née Lemoine (c. 1761 – 30 May 1811) was a French painter.
Gabiou was the sister of painters Marie-Denise Villers and Marie-Victoire Lemoine, and was the sister-in-law and cousin of Jeanne-Elisabeth Chaudet; her husband, whom she married in 1789, was Chaudet's brother Jean-Frédéric Gabiou. Her work is usually signed "Eli Lemoine" or "Elith Lemoine", and her name is easily mistaken for that of Élisabeth Lemoine, née Bouchet. She has been described as a pastellist, though no pastels are known to exist by her hand.[1] A supposed self-portrait appeared at auction through Christie's in 2010, realizing a price of €17,500.[2]
