The Cabinet are individuals of Barbados which execute the duties of the Government of Barbados. Under a Parliamentary republic , these powers are vested nominally by the President of Barbados, but are exercised in practice by a Cabinet of Ministers, presided over by the Prime Minister of Barbados. The Prime Minister is formally appointed by the President: the President must appoint, as Prime Minister, someone who can control a majority of votes in the House of Assembly. In practice, this is normally the leader of the largest political party or coalition in the house. When there is no clear majority, the president assumers the role of arbitrator and opens negotiations with the leaders of the various political parties, in the hope of finding someone whom a majority will accept as Prime Minister. In the event of that failing to take place, the President must dissolve the House of Assembly and call an early election.

The Cabinet system of government was implemented in the colony of Barbados on 1 February 1954 leading to attainment of full self-government. Prior to an official Cabinet, the role was fulfilled by the colonial era Executive Council on the island.^[1] Under the Constitution of Barbados, Cabinet is not prescribed a maximum number Cabinet of Ministers, however, it must have no fewer than five members. The first Cabinet of Barbados was led by Premier Sir Grantley Herbert Adams.^[2] The four other Ministers were:

• The Hon. Dr. H.G.H. Cummins (Member 1935–36; 1940–1961);
• The Hon. Mencea Ethereal Cox (later Sir Mencea,^[3] member 1944–1961; senator 1976–1981;
• The Hon. R. G. Mapp (later Sir Ronald, member 1946–1961; Senator 1976–1979);
• The Hon. C. E. Talma (later Sir Edwy, member 1944–1948; 1951–1976)

Between 30 November 1966 and 30 November 2021, after Barbados was granted independence, under a Westminster system of governance, the ceremonial Head of State was Elizabeth II, Queen of Barbados (represented by the Governor-General) while the office of the Premier became the Prime minister as it is now presently known. After Barbados transitioned to a republic on 30 November, 2021, the Monarchy of Barbados was abolished along with the office of the Governor-General with the Governor-General's duties and powers transferring to the President of Barbados who became head of state.
