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.

The Parliament of Barbados is the national legislature of Barbados. It is accorded legislative supremacy by Chapter V of the Constitution of Barbados. The Parliament is bicameral in composition and is formally made up of two houses, an appointed Senate and an elected House of Assembly, as well as the President of Barbados who is indirectly elected by both. Both houses sit in separate chambers in the Parliament Buildings, in the national capital Bridgetown in Saint Michael.
