Derekom was a winter pasture located in the territory of the Gazakh uezd of the former Yelizavetpol (Ganja) governorate, later in the former Chambarak (Krasnoselsk) district, and currently in the Gegharkunik province. It is located in the village of Tokhluja (Drakhtik), on the shores of Lake Goycha.

The toponym was coined by combining the word “dere” used in the sense of “a valley” in Azerbaijani and the word “kom” used in the sense of “a pen, place where sheep are kept”.
