Deputy Commissioner (popularly abbreviated to "DC") or District Magistrate (জেলা প্রশাসক ও জেলা ম্যাজিস্ট্রেট)[1] is the chief administrative and revenue officer of a district or an administrative sub-unit of a division.

During the early year, before the Bangladesh era, the deputy commissioner's office used to be concerned with internal security and revenue administration.

Over time, however, the office has become increasingly occupied with the general welfare of the people in the district.

The Deputy Commissioner is a representative of the Government in the field of law and order, land administration, disaster management and general and local elections.

The Deputy commissioners are appointed from the members of the Bangladesh Civil Service (Administration).
