The Monchino or Monchinu is a breed of horse indigenous to the Valle de Guriezo in the Cantabria region of northern Spain, but extending into neighbouring Biscay province. It is listed in the Official Catalogue of Livestock Breeds of Spain (Catálogo Oficial de Razas de Ganado de España) in the group of autochthonous breeds in danger of extinction. The word monchinu means highlander, from the mountains, in Cantabrian.
Horse breeds thought to originate wholly or partly within the Iberian peninsula.
Some have complex or obscure histories, so inclusion here does not necessarily imply that a breed is predominantly or exclusively Iberian.
