Junín de los Andes is a first category municipality and administrative center of the Huiliches Department in the province of Neuquén, Argentina.

Prior to the expansion of the Argentine state into Patagonia at the end of the 19th century, the Mapuche and Tehuelche hunting and gathering tribes coexisted in the region.

The military authorities originally wanted to name it General Frías, but ultimately changed it to Junín de los Andes, inspired by the Aymara vocable hunins, meaning pasture.

[5] The surrounding territory is divided into three landscape zones: the east, characterized by plateau basalt with its fluvial valleys, formed by wind erosion, where mountains and small hills are seen; the center, which is a valley glacier area with rivers and creeks and their mallín-vegetated banks; and the west, where the volcanoes such as the Lanín (3,776 metres (12,388 ft) above sea level) and lakes prevail.

On its basement lie more recent minerals, such as vulcanites, covering glaciofluvial sediments and elements formed by effusion in the quaternary age.

[9] The Huiliches Department has a remarkable scenic beauty typical of the northern Patagonic Andes, characterized by its vegetated hill slopes.

[8] Junín de los Andes is considered a traditional cattle farming area within the province, hosting the Neuquén Rural Society and its annual exposition since 1942.

[3][17] The Lanín National Park among other natural attractions make the region a popular destination for trekking, hiking and other outdoor activities.

[18] Given the excellent fishing possibilities in the Chimehuín river and the near located lakes, the village is known as Argentina's national sport trout-fishing capital, offering services for the activity.

[19] The traces of Mapuche culture and Argentine pioneers tradition, to which the town owes its origins can be found in everyday life in artistic expressions and their inhabitants.

[23] The remains of beatified young Mapuche Ceferino Namuncurá rest on the foot of a hill in the small village San Ignacio, located nearly 60 km from Junín de los Andes.

The sanctuary was designed as a giant cultrun drum with wooden walls, sheet steel roofing and rhombus-shaped windows with multicolor glass.

[25] Some of the historical buildings dating back to the early years of Junín de los Andes, such as the first post office (1901) are still on foot.

[27] The Camp Tender Festival, held in February, also celebrates the rural traditions, depicting jineteada, Argentine folk-music and other aspects of the gaucho lifestyle.

[29] The National Route 40 runs north–south through the city, connecting it with Zapala to the north and San Martín de los Andes to the south.
