Añelo is a municipality in Neuquén Province, Argentina. It is the seat of Añelo Department and is classified as a second category municipality.
The city lies in the Neuquén region of western Argentina, within the broader Patagonian area of the country. It serves as the administrative centre for its surrounding department.
Añelo has become notable in recent years because of its location within the Vaca Muerta shale formation, one of the largest unconventional oil and gas reserves in the world. The resulting energy development has brought significant activity and population growth to the area, changing the character of what was historically a small settlement in the Patagonian steppe.
