Akatuy katorga prison (Russian: Акатуйская каторжная тюрьма, Akatuyskaya katorzhnaya tyur'ma) was part of the Nerchinsk katorga system of the Russian Empire in the Nerchinsk okrug of Transbaikalia. It was constructed in 1888 at the Akatuyskom mine, what is now the village of New Akatuy (Новый Акатуй). Originally labor convicts (mostly criminal) were used here for extraction of lead-silver ores. After the closing of the Kara katorga in 1890, it became one of the main centers of detention of political prisoners.
