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.

The monarchy of Barbados was a system of government in which a hereditary monarch was the sovereign and head of state of Barbados from 1966 to 2021. Barbados shared the sovereign with the other Commonwealth realms, with the country's monarchy being separate and legally distinct. The monarch's operational and ceremonial duties were mostly delegated to her representative, the governor-general of Barbados.
