Dalstroy (, ), also known as Far North Construction Trust, was an organization set up in 1931 by the Soviet NKVD (the predecessor of the KGB) in order to manage road construction and the mining of gold in the Chukotka region of the Russian Far East, now known as Kolyma. Initially it was established as State Trust for Road and Industrial Construction in the Upper Kolyma Area. After the 1952 reorganization it was known as Main Directorate of Camps and Construction of the Far North.
