The Federal Senate is the upper house of the National Congress of Brazil. When created under the Imperial Constitution in 1824, it was based on the House of Lords of the British Parliament, but since the Proclamation of the Republic in 1889 and under the first republican Constitution the Federal Senate has resembled the United States Senate.

The National Congress is the legislative body of Brazil's federal government. Unlike the state legislative assemblies and municipal chambers, the Congress is bicameral, composed of the Federal Senate and the Chamber of Deputies. The Congress meets annually in Brasília from 2 February to 22 December, with a mid-term break taking place between 17 July and 1 August.
