Hayanist (hy|Հայանիստ) is a village in the Masis Municipality of the Ararat Province of Armenia. The distance from Yerevan is 15.4 km. Despite the favourable location of the community (proximity to Yerevan and abundance of good agricultural land), most households cannot provide for their living and heads of families often chose the labour migration as the only solution of their problems. Around 160 hectares of the community's agricultural land are not irrigated.
The village was originally known as Gharaghshlar, Gharaghshlagh, or Kara-Kishlak (hy|Ղարաղշլաղ|translit=Ġaraġšlaġ; ru|Каракишляг|translit=Karakishlyag; az|Qaraqışlaq[2]), meaning black kishlak. In 1978, the village was renamed Dostlug or Dostlugh (Dostluq, meaning "friendship"); finally, it received the name Hayanist in 1991 following the exodus of its Azerbaijani population.
Hayanist, then known as Kara-Kishlak, was part of the Erivan uezd of the Erivan Governorate within the Russian Empire. Bournoutian presents the statistics of the village in the early 20th century as follows:
