Horomos is an Armenian monastic complex, located about 15km northwest of Ani in the central district of the province of Kars close to the Turkish-Armenian border. It used to be one of the most important religious and cultural centers of the Armenian kingdom of Ani.

The monastery was built by the architect Hovhannes in the 10th century, during the reign of King Abas I (943-953).
During the genocide, the monastery sustained heavy damage and gradually became a part of the Turkish government. With time, some buildings were completely destroyed, but the monastery has been partially preserved.
