Valtierra is a town and municipality in the province and autonomous community of Navarre, in northern Spain. It is located in the Ebro Valley region of Navarre, near the border with Aragon.
The town sits close to the Ebro River and is known for the Valtierra area's semi-arid landscape, which contrasts with the greener terrain of much of northern Navarre. The municipality includes the small settlement of the Bardenas Reales area nearby, a semi-desert region that is one of Navarre's most distinctive natural features.
Valtierra's economy has traditionally been based on agriculture, with cereal crops and vineyards among the main activities. The town also lies near the Navarra Circuit, a motorsport race track located within the municipality, which has hosted major motorcycle and car racing events.
