Ortundere is a valley in the Iravan uezd of the former Iravan governorate, later in the former Vedi (Ararat) district, and currently in the Ararat province. It is located on the north-eastern side of the Yukhari Chanakhchi (Sovetashen) village.

The toponym was coined by combining the word “ortun” used in the sense of “middle” in Turkic and the word “dere”.
