Antoine Vestier was a French miniaturist and painter of portraits, born at Avallon in Burgundy, who trained in the atelier of Jean-Baptiste Pierre. He showed his work at the Salon de la Correspondance, Paris, before being admitted (agréé) to the Académie Royale de Peinture et de Sculpture in 1785, when a portrait of the painter Gabriel François Doyen, was his morceau de réception.

Among his sitters was the royal cabinet-maker, Jean Henri Riesener (1786, Musée de Versailles).

Vestier was the father of portraitist Marie-Nicole Vestier, wife of miniaturist François Dumont.
