The prime minister of Barbados is the head of government of Barbados. The prime minister is appointed by the president under the terms of the Constitution. As the nominal holder of executive authority, the president holds responsibility for conducting parliamentary elections and for proclaiming one of the candidates as prime minister.
Sir Grantley Herbert Adams was appointed Barbados' first Premier on 1 February 1953 when Barbados attained full self-government. When Barbados negotiated full political independence from Britain on 30 November 1966, the office was renamed Prime Minister. Despite the renaming, the functions of the office were not significantly changed.
As a former British colony, Barbados has largely adopted British political models and follows the Westminster, or Cabinet, system of government, in which the executive branch of government is responsible to the legislature. The prime minister was historically appointed by the governor-general until 2021, and by the President of Barbados thereafter, to serve a maximum five-year term in Parliament. The president must endeavour to find a candidate acceptable to a majority in the House; if no such candidate can be found, the president must dissolve Parliament and call an election prematurely.
Incumbent prime ministers who lose their seat in a parliamentary election may not be prime minister. If the prime minister dies, as has happened on three occasions, the president appoints a replacement from Parliament to serve the remainder of the five-year term of Parliament. The prime minister must also be supported, or at least accepted, by a majority in the House of Assembly. If at any time the prime minister loses the "confidence" of the House, he must resign, along with the entire Cabinet. In practice, this usually reduces the prime minister's appointment to a formality, as the parliamentary leader of the majority political party or coalition is invariably appointed. If, however, no such majority party or coalition exists, whether due to electoral fragmentation or to party realignments after an election, the president's role becomes much more important.
The prime minister of Barbados is technically the "first among equals," whose vote in meetings of the Cabinet carries no greater weight than that of any other minister. In practice, the prime minister dominates the government. Other ministers are appointed by the president, but on the prime minister's "advice", and may be dismissed by the prime minister at any time (although hypothetically, the prime minister's control over ministerial appointments may be tempered by the realities of coalition politics: the leader or leaders of coalition partners may insist on having a say in the matter too).
There were three premiers prior to independence and there have been eight prime ministers since independence. The living former prime ministers of Barbados are the Right Honourable Lloyd Erskine Sandiford and the Right Honourable Freundel Stuart. The current holder of the office is the Honourable Mia Mottley Q.C., M.P.
The prime minister advises the president, appoints ministers, controls a majority in the House of Assembly, and appoints 12 senators. Although the prime minister is appointed by the President of Barbados, they are almost always the leader of the majority party.

Prior to the establishment of the Caribbean Court of Justice in 2005, it was common for Barbadian prime ministers to be nominated to the British Privy Council, whose large membership includes prominent British persons and persons from other Commonwealth nations that continue to share the same person as monarch.
