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.

The president of Barbados is the head of state of Barbados and the commander-in-chief of the Barbados Defence Force. The office was established when the country became a parliamentary republic on 30 November 2021. Before, the head of state was Elizabeth II, Queen of Barbados, who was represented on the island by a governor-general. The first and current president is Sandra Mason, who previously served as the last governor-general.
