The Government of Barbados (GoB), is a unitary parliamentary republic, where the President of Barbados is the head of state and the Prime Minister of Barbados is the head of government.

The Senate of Barbados is the upper house of the bicameral Parliament of Barbados. The Senate is accorded legitimacy by Chapter V of the Constitution of Barbados. It is the smaller of the two chambers. The Senate was established in 1964 to replace a prior body known as the Legislative Council. Besides creating and reviewing Barbadian legislation, the Senate generally reviews approved legislation originating from the House of Assembly. One main constraint on the Senate is that it cannot author monetary or budget-related bills. Most of the non-political appointees to the Senate have been selected by the Governor-General from civil society organisations, labour collectives and public associations in Barbados.
