Defunct The Navarrese People's Union (Spanish: Unión del Pueblo Navarro; Basque: Nafar Herriaren Batasuna), abbreviated to UPN, is a regional conservative[2] political party in Navarre, Spain.

The party's regionalist tradition dates back to the nineteenth century, in which the Spanish nation is seen to be based on 'regional liberties'.

As part of an agreement held over the 1991–2008 period, the PP did not run in any elections in the Navarra Congress Electoral District and People's Party of Navarre (founded in 1989) was dissolved, while UPN were on the same national ticket as the PP at the Spanish national elections.

The pact was terminated in October 2008 as a result of UPN refusal to vote alongside the PP in the Spanish Congress of Deputies to reject the government budget presented by José Luis Rodríguez Zapatero's cabinet.

A major factor in the new agreement was the two parties' desire to prevent Bildu from winning enough seats to form a parliamentary group.
