The Campine is a breed of domestic chicken originating in the northern part of Belgium. It is named for the Campine region of north-eastern Belgium and south-eastern Netherlands. It was known there as the Kempisch Hoen.

Auto-sexing breeds of poultry are those in which the sex of newly-hatched chicks can be determined from the colour and markings of the down. Some breeds of chicken, of goose and of domestic pigeon have this characteristic. The idea of such a breed is due to Reginald Punnett, who created the first auto-sexing chicken breed, the Cambar, at the Genetical Institute in Cambridge in 1928.
