St. Mary Church is an ancient Assyrian church located in the city of Urmia, West Azerbaijan province, Iran.
The current old building of the church belongs to the Sasanian era and its interior design is a combination of Sasanian and Arsacid architecture.
A Chinese princess, who contributed to its reconstruction in 642 AD, has her name engraved on a stone on the church wall. The famous Italian traveller Marco Polo also described the church in his visit.
