The Blue Andalusian, Spanish: Andaluza Azul, is a breed of domestic chicken indigenous to the autonomous community of Andalusia in south-west Spain.

It is distributed through much of the countryside of Córdoba and Seville, and is concentrated particularly in the area of Utrera, which is considered the heartland of the breed.

[6] Two breeders in particular are thought to have started this process, which took many years: one named Coles, from Fareham, Hampshire, and a certain John Taylor of Shepherd's Bush, in west London.

[10] Andalusians reached the United States in about 1850–1855, and were included in the first edition of the Standard of Perfection of the American Poultry Association in 1874.

[6] The earlobes of the Andalusian are smooth, white, and almond-shaped; the crest is single and of medium size, with five well-defined points.
