Gai ( ), known as Khatunarkh until 1978 (and also spelled Guy or Gay or Kai), is a village in the Armavir Province of Armenia. It was founded in the 1670s, and named for the wife of Sefi Khan, Safavid governor of Chokhur-e Sa'd. In 1978, it was renamed in honour of Russian Civil War hero Hayk Bzhshkian, whose nom-de-guerre was Gai.
