The Orpington is a breed of chicken named after the town of Orpington, Kent, in south-east England, which was made famous in part by this breed. It was bred to be an excellent layer with good meat quality. Its large size and soft appearance together with its rich colour and gentle contours make it very attractive, and as such its popularity has grown as a show bird rather than a utility breed. Hens often become broody and are good mothers. Although rather heavy, they are able to fly small distances but rarely do so.

The original Black Orpington was bred by William Cook in 1886 by crossing Minorcas, Langshans and Plymouth Rocks to create a new hybrid bird. Cook selected a black bird that would exhibit well by hiding the dirt and soot of London. When the breed was shown in Madison Square Gardens in 1895, its popularity soared. Cook also bred the Orpington Duck.
