The Chamber of Deputies is a federal legislative body and the lower house of the National Congress of Brazil. The chamber comprises 513 deputies, who are elected by proportional representation to serve four-year terms. The current President of the Chamber is the Deputy Arthur Lira (PP-AL), who was elected on 1 February 2021.

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.
