Saint-Étienne-de-Baïgorry (Basque: Baigorri) is a town in the Pyrénées-Atlantiques department in French Basque Country, historically part of the province of Lower Navarre. Nestled in the Aldudes valley on the Nive des Aldudes river, it sits near the Spanish border, with access to the Baztan valley in Spain via the Izpegi Pass.

The town's Basque name, Baigorri, means "red bank of the river," referring to the river Nive.

A historic town whose Viscounty was created in 1033 by King Sancho III of Navarre, Saint-Étienne-de-Baïgorry has a strong Basque identity. This connection is celebrated annually at the Nafarroaren Eguna (Day of Navarre), a major festival held in early May. It attracts thousands of people from both the French and Spanish sides of Navarre to strengthen cultural ties and affirm their shared heritage.

The town was the chief town of its own canton before it was merged into the canton of Montagne Basque in 2015.
