Alexandre-François Desportes was a French painter and decorative designer who specialised in animals.
Desportes was born in Champigneulle, Ardennes. He studied in Paris, in the studio of the Flemish painter Nicasius Bernaerts, a pupil of Frans Snyders. During a brief sojourn in Poland, 1695–96, he painted portraits of John III Sobieski and Polish aristocrats; after the king's death Desportes returned to Paris, convinced that he should specialise in animals and flowers. He was received by the Académie de peinture et de sculpture in 1699, with the Self-Portrait in Hunting Dress now in the Musée du Louvre. In 1712–13 he spent six months in England. He received many commissions for decorative panels for the royal châteaux: Versailles, Marly, Meudon, Compiègne and, his last royal commission, for Louis XV at Choisy, 1742. He also did decorative paintings for the duc de Bourbon at Chantilly. Both Louis XIV and Louis XV commissioned portraits of their favorite hunting dogs.
