Haghartsin (Armenian: Հաղարծին) is a village in the Dilijan Municipality of the Tavush Province of Armenia. The 13th-century Haghartsin Monastery is located around 8 km northwest of the village.
It was founded in 1815 as Jarkhech by Prince Jar Artsruni. In 1940, the village was renamed Kuybyshev after the Soviet politician Valerian Kuybyshev.[2] In 1992, the village was renamed Haghartsin, after the nearby Haghartsin Monastery.
