The Cabinet Division (Bengali: মন্ত্রিপরিষদ বিভাগ) is the executive office of the Prime Minister of Bangladesh. As a division of the Government of Bangladesh, the office is responsible for the executive administration of the government and facilitating smooth transaction of business in the Cabinet. The division assists in decision-making in government by ensuring inter-ministerial coordination, ironing out differences amongst ministries/departments and evolving consensus through the instrumentality of the standing/ad hoc committees of secretaries. The Cabinet Secretary, assisted by seven Additional Secretaries, heads the Cabinet Division under the Prime Minister as the minister in-charge.

In 1972, the Ministry of Cabinet Affairs was created to provide secretarial assistance to the government of Bangladesh. After 1975, it was placed under President's Office.

After 1991, the presidential system of government by Act of Parliament was abolished, and by October 1991, Cabinet Division was formed as a full-fledged administrative unit.

The Cabinet Division is responsible for writing and maintaining the Secretariat Instructions. This document outlines how ministries and divisions should interact with each other. Its purpose is "to ensure uniformity and efficiency in the observance of administrative practices and procedures". It supplements the Rules of Business, and all business of government is to be transacted in accordance with these two instruments. The secretary (the senior civil servant) in each ministry and division is responsible for ensuring the Secretariat Instructions are followed.
