Jean-Ferdinand Chaigneau, born March 6, 1830 in Bordeaux, by Victorine Goethals and Jean-Frédéric Marius Chaigneau, and died October 23, 1906 in Barbizon, is a French painter and engraver of the Barbizon School.

He was particularly famous during his lifetime for his art of animal painting, characterized by his talent for staking out herds of sheep from the plain of Chailly, in the sites he painted, a process that is somehow his trademark. He is also a popular engraver, author of a six-sheet album.

Ferdinand Chaigneau died on 23 October 1906 in Barbizon, the village where he lived, and was buried there with his daughter Suzanne. In addition to French museums, his paintings are held in North American public collections as well as in Brazil and Japan.
