The Parliament of India (IAST: Bhratya Sansad) is the supreme legislative body of the Republic of India. It is a bicameral legislature composed of the president of India and two houses: the Rajya Sabha (Council of States) and the Lok Sabha (House of the People). The president in his role as head of the legislature has full powers to summon and prorogue either house of Parliament or to dissolve the Lok Sabha. The president can exercise these powers only upon the advice of the prime minister and his Union Council of Ministers.

Those elected or nominated (by the president) to either house of Parliament are referred to as members of Parliament (MPs). The members of parliament of the Lok Sabha are directly elected by the Indian public voting in single-member districts and the members of parliament of the Rajya Sabha are elected by the members of all state legislative assemblies by proportional representation. The Parliament has a sanctioned strength of 543 in the Lok Sabha and 245 in the Rajya Sabha including 12 nominees from the expertise of different fields of literature, art, science, and social service. The Parliament meets at Sansad Bhavan in New Delhi.
