Ekostrovskaya Volost (Russian: Экостровская волость) was an administrative division (a volost) of Kemsky Uyezd of Arkhangelsk Governorate of the Russian Empire, which existed in 1866–1868.[1]
It was established in 1866 when Ekostrovskoye Rural Community was transformed into a volost. In 1868, together with Voronyinskaya Volost and Pechengskaya Volost it was merged into a newly created Kolsko-Loparskaya Volost.
