The Ixworth is an English breed of chicken created in 1932 by Reginald Appleyard. It is named after  Ixworth, a village in Suffolk. It was bred from white Sussex, white Minorca, white Orpington, Jubilee, Indian Game and white Indian Game chickens. In the 1970s, the Ixworth chicken nearly became extinct. It has gradually recovered with the help of conservationists. However, it is still classified as an endangered native breed by the Rare Breeds Survival Trust. According to this conservation charity, there are only 20 enthusiastic breeders.

The Ixworth is a hardy medium to large breed with a quiet temperament. It has pure white plumage and white legs with a pinkish tinge. Its comb and eyes are red.

The Ixworth is prized for the high quality of its meat. The hens produce about 150 -180 medium-sized eggs in a year.
