The Poule d'Estaires (French pronunciation: [pul detɛʁ]) is a breed of domestic chicken from the Nord-Pas-de-Calais region of north-eastern France.

It is a variety of the Langshan breed imported to England from China in 1872, and exported from there to Europe soon after.

A breeders' club was formed in 1999, and in 2004 the breed came under the protection of the Centre Régional de Ressources Génétiques, the genetic resource centre of the Nord – Pas de Calais region.

The Estaires breed is closely similar to the Croad Langshan: the comb is small and regularly serrated, the legs are dark slate-blue or almost black and are slightly feathered.

The plumage is black with beetle-green lights;[3] there are also gold- and silver-necked colour variants.
