Marguerite Chapuy (21 July 1852, Bordeaux – 23 September 1936, Dijon) was a French operatic soprano and the daughter of a former dancer at the Opéra.

She undertook lessons with Arnoldi (her first teacher having been Belloni), and during the Franco-Prussian War of 1870 she moved to Brussels, where she continued her vocal studies, followed by stage appearances in Rennes.

After the initial run of Carmen, Chapuy sang Rosina in The Barber of Seville in July 1875 at the Drury Lane Theatre, London.
