Ernest Chaplet (1835 in Sèvres – 1909 in Choisy-le-Roi) was a French designer, sculptor and ceramist. He was a key figure in the French art pottery movement, and his works are held in international public collections such as the Musée d'Orsay, Paris. From 1887 Chaplet took up permanent residence at Choisy-le-Roi, often collaborating with the ceramics manufacture Alexandre Bigot. He won acclaim at the 1900 International Exhibition, but lost his sight in 1904, after which his son Emile Lenoble took over his studio. He committed suicide in 1909.
