The Burguete (Spanish; Castilian: '''Caballo Burguete'''|italic=no or Spanish; Castilian: '''Caballo de Raza Burguete'''|italic=no, Basque: '''Aurizko zaldia'''|italic=no) is a Spanish breed of horse from the autonomous community of Navarre in north-eastern Spain. It is listed in the Catálogo Oficial de Razas de Ganado de España in the group of autochthonous breeds in danger of extinction. It is reared principally for horsemeat. The name, both in Basque and in Spanish, is derived from that of the municipio of Auritz/Burguete.
It is one of four Basque breeds of horse, the others being the Jaca Navarra, the Pottoka and the Basque: Euskal Herriko Mendiko Zaldia|italic=no or Basque Mountain Horse.
The Burguete derives from cross-breeding of indigenous Basque mares of Jaca Navarra type with foreign stallions of the Trait Breton, Postier Breton and Percheron breeds, and later with Ardennes and Comtois stock. It received recognition from the national government of Spain in 1979, when it was included in the Catálogo Oficial de Razas de Ganado de España. The name of the breed, both in Basque and in Spanish, is derived from that of the municipio of Auritz/Burguete in north-eastern Navarre.
A breeders' association, the Asociación de Criadores de Raza Equina Burguete de Navarra, was established in 1998, and in 1999 was recognised by the Government of Navarre and authorised to keep the stud-book for the breed.

The Burguete is solidly built and somewhat brachymorphic – the length of the body is rather more than the height at the withers. The coat is either bay or chestnut.
