Iruya is a small town of population 1,070 in northwestern Argentina. Located in the altiplano region along the Iruya River, Iruya sits nestled against the mountainside at an elevation of 2,780 meters (9,120 feet). The Altiplano (Spanish for "high plain") or Andean Plateau, in west-central South America, is the area where the Andes are the widest.

There is no direct road connection to the rest of the Salta province and access is through a road to the adjacent Jujuy province, a 50 km (31 mi) portion of which is unpaved. Nonetheless, the town is popular with tourists for its scenic location and townscape and friendly locals.

The first aboriginal inhabitants, descendants of the Incas, settled here in the mid-1600's but the town itself was not founded until 1753. The town's church, Iglesia Nuestra Senora del Rosario y San Roque, was built in 1690. In 1995, the town of Iruya was declared a National Historic Site.
