Chavín de Huántar or Chavín culture is an archaeological culture of Ancient Peru that was developed during the Early Horizon (1200 BC-200 BC) It had its development center in the city of Chavín de Huántar, which is located at 2 km from the confluence of the Huachecsa and Mosna rivers, in the upper basin of the Marañón river.

The ceremonial center of the Chavín culture, Chavín de Huántar, is located in the Conchucos area, on the eastern side of the Cordillera Blanca, at the confluence of the Mosna and Huachecsa rivers, tributaries of the Marañón river; in the current district of Chavín de Huántar, in the province of Huari (Áncash region).

The culture of Chavín extended through a large part of the Andean region, covering the north to the current Peruvian departments of Lambayeque and Cajamarca and the south to the current Peruvian departments of Ica and Ayacucho, which is why it is considered a Panandina culture. It is not clear that in all the places where the Chavín culture is appreciated, the language and ethnicity of the inhabitants of Chavín de Huántar were predominant
