The Salazar Valley (Basque: Zaraitzu Ibarra, Spanish: Valle de Salazar) is a valley in the east of the Foral Community of Navarre in Spain.

The Sierra de Abodi, part of the Western Pyrenees, forms the natural boundary in the north.

The first mention of the name was in documents of the Monastery of Leire, with the denomination of Sarasazo (924).

The Castilian official denomination began being used widely in the 17th century probably influenced by the Salazar surname, famous in the Nobility of the Iberian Peninsula.

However, the last publications of works about the Basque of Zaraitzu (dictionary, learning method, text collection and oral recordings) and some courses of this dialect in the valley have been addressed to the local population in order to maintain it to some extent.
