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.

She has been described as a pastellist, though no pastels are known to exist by her hand.
