The French: '''Poule d'Estaires'''|italic=no (pronounced as /fr/) 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. Some were raised in the Pas-de-Calais département, and others in the neighbouring Nord département, particularly in the areas of Estaires, La Gorgue, Laventie and Merville, from which birds were supplied to Lille.
A breeders' club was formed in 1999, and in 2004 the breed came under the protection of the French: Centre Régional de Ressources Génétiques|italic=no, 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; there are also gold- and silver-necked colour variants.
