Fustiñana is a town and municipality in the province and autonomous community of Navarre, in northern Spain. It lies within the Ebro Valley region of Navarre, near the banks of the Ebro River.
Like many settlements in this part of Navarre, Fustiñana has a history tied to the medieval Kingdom of Navarre and to the agricultural traditions of the Ebro basin. The surrounding landscape is characterised by irrigated farmland and riverine terrain typical of the region.
The town is one of several small municipalities in the Tudela area of southern Navarre, a comarca known for its vegetable cultivation and its arid, continental climate. Fustiñana remains a modest local community rather than a major tourist destination.
