The Hamburg, Dutch: Hollands hoen, German: Hamburger, is a breed of chicken which is thought to have originated in Holland sometime prior to the fourteenth century.

Eleven different colour varieties are recognised in Germany and Holland, including silver-spangled, gold-spangled, gold-pencilled, citron-pencilled, silver-pencilled, white, black and citron-spangled;[6] six of these are included in the American standard of perfection.

[5] Pencilled breeds are smallest and self-coloured birds are largest.

[3][10] Hamburgs mature quickly and are considered good egg producers.

Lalia Phipps Boone argued in 1949 that Chauntecleer and Pertelote, the chickens in Chaucer's "Nun's Priest's Tale," are Golden Spangled Hamburgs.
