Tayagaya was a winter pasture located in the territory of the Novo-Bayazid uezd of the former Iravan governorate, later in the former Chambarak (Krasnoselsk) district, and currently in the Gegharkunik province. It was located near the village of Ardanish.

The pasture was inhabited by nine Azerbaijanis in 1926. It was dissolved as a settlement in the 1930s.

The toponym was coined by combining the word “taya” used in the sense of “a stack of stones” and the word “gaya” used in the sense of “a mountain, rock, stone, small mountain”.
