The prime minister of Mauritius is the head of government of Mauritius. He presides over the Cabinet of Ministers, which advises the president of the country and is collectively responsible to the National Assembly for any advice given and for all action done by or under the authority of any minister in the execution of his office.

The National Assembly is Mauritius's unicameral legislature, which was called the Legislative Assembly from 1968 until 1992, when the country became a republic. Prior to 1968 and under British rule it was known as the Legislative Council. The Constitution of Mauritius provides for the parliament of Mauritius to consist of the President and the National Assembly. The parliament of Mauritius is modelled after the Westminster system of parliamentary democracy, where members of parliament are voted in at regular general elections, on the basis of a first past the post system. The working language of the National Assembly is English.
