The Chapel of Dzordzor (Armenian: Ծոր Ծորի Սուրբ Աստվածածնի մատուռ, Persian: کلیسای زور زور) is part of an Armenian monastery located in Maku County, West Azerbaijan province, Iran, on Zangmar River near the village of Baron.

The construction of this chapel cross surmounted in the center of a drum dome dates back to the 9th to 14th centuries.

The chapel is on the World Heritage List of UNESCO since July 6, 2008, alongside St. Thaddeus and St. Stepanos monasteries under the name Armenian Monastic Ensembles of Iran.

The construction was ordered by the bishop of the Saint Thaddeus monastery named Zecharia who was from a local noble landowning family.

Like most of the Armenian churches of that era, this chapel is constructed with cut stones of varied sizes, and has very simple exterior decorations.
