Yelpin (; Armenian: Ելփին) is a village in the Areni Municipality of the Vayots Dzor Province in southwestern Armenia, located on the Armenia–Azerbaijan border.
Yelpin community was established in 1828, after the Russo-Persian War (1826-1828). The founders (ethnic Armenians) fled from the Persian regions of Khoy and Salmas. The community was founded in the place of the village of Nrbuyn, and inherited its name, which gradually transformed to Nrbuyn, Nrbin, Irpin and finally to Yelpin. 13th-century Armenian historian Stephen Orbelian, in his book Patmutyun Sisakan (History of Sis) mentions Adopen, Khndzorut, Kechut, Chochanak, Chavadzor, Mokhrot and other historical places to be located in the administrative territory of Yelpin. However, the territory of Yelpin has been inhabited since the Stone Age, evidence of which can be found in numerous caves in the vicinity. The Bronze Age is the best represented and archaeological expeditions are very active in the area. Found here are numerous artifacts, such as stone and metal instruments, arms, pottery and many others, which are kept in the Yeghegnadzor ethnographic museum.
The community is surrounded by monasteries and structures having cultural value. To the northwest of the village, remnants of a medieval fortress can be found, 10 km away there are numerous ancient decorated gravestones. Following the old road to Aghavnadzor, remnants of the Geshin settlement can be found, with a famous cave nearby․ To the southeast of the village, there is the 14th-century sanctuary of Toukh Manuk and medieval Didivan monastery in Gndasar, preserved from the times of the Bagratuni dynasty. The Noravank monastic complex (12th century) is located nearby, which is a UNESCO heritage site. In 2005 a new church was built in the village center.
