Matosavank (Armenian: Մաթոսավանք) is 13th-century small Armenian monastery, hidden in a forested area of Dilijan National Park 3 km northwest from the town of Dilijan in the Tavush Province of Armenia. It sits close to the monastery of Jukhtak Vank as well as to a nearby cemetery. The church is currently in ruins and is relatively difficult to find since trail markers are often misleading.

Matosavank was constructed with the oversight of Avag, the son of Ivane of the Mkhargrdzeli dynasty after having vowed his submission to the Mongol invading armies. He later became the military leader of Georgian and Armenian combined forces under Möngke Khan, the fourth Great Khan of the Mongol Empire.
