The Jaca Navarra (Basque: Nafarroako zaldiko), or Navarrese horse, is a breed of small horse from the Navarre region of northern Spain. It is listed in the Catálogo Oficial de Razas de Ganado de España in the group of autochthonous breeds in danger of extinction. The total population of the Jaca Navarra has been variously estimated at 350 (in 1999), 250 (in 2000), and 240 and decreasing (in 1997). In April 2011 the total population was reported to be 899, all of which were in Navarre. The breed is listed by the FAO as Endangered.
A breeders' association, the Asociación de Criadores de Ganado Equino Jaca Navarra (JACANA), was formed in 1999, and a breed register opened in 2001. The conservation and reference herd kept in semi-feral conditions at the Sabaiza estate contains all but a few examples of the breed.
In Spanish, this breed is also known as the Poney Navarro, Caballo Navarro, Caballo Vasco-navarro, Caballito de Andía, Caballito de las Améscoas or Caballito de la Barranca, and was in the past also known as Jaca de Montaña, Raza de Pamplona or Raza Pamplonica.
The word jaca has an unusual history, from Old Spanishhaca, itself from Old Frenchhaque, which in turn is ultimately derived from the English place-name Hackney, a place famous for its horses.
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.
