The Department of Cooperative (DOC) is the principal government organization responsible for the promotion & development of cooperative societies in Bangladesh. The DOC works directly under the supervision and control of the Rural Development & Cooperative Division (RDCD) of the Ministry of Local Government, Rural Development & Cooperatives. In 1986, the functions and the activities of the DOC were brought under the management of a professional cadre known as Bangladesh Civil Service (BCS) Cooperative Cadre. A total of 189 cadre officers are now employed in the DOC. The total manpower of the DOC is around 4508.

The DOC is headed by a Registrar who is a civil servant not below the rank of a Joint Secretary to the Government of Bangladesh. There are four Additional Registers below the Registrar. 

There are four divisional Cooperative offices (at Dhaka, Chittagong, Rajshahi and Khulna) throughout the country. Each of these offices is headed by a Divisional Joint Registrar. Below there are two Deputy Registrars and one Assistant Registrar working in each of the Divisional Offices. There are sixty four District Cooperative Offices throughout the country. Each of the districts is headed by a District Cooperative Officer (an Assistant Registrar) who is the registering authority of all Primary Cooperative Societies under that district. Furthermore, there are cooperative offices at each of the 479 Upazilas throughout the country. There is a National Cooperative Academy and 9 (nine) Cooperative Zonal Training Institutes under the DOC at various locations of the country.
