The 56th Legislature of National Congress was a meeting of the legislative branch of the Federal Government of Brazil, composed by the Federal Senate and the Chamber of Deputies. It convened in Brasília on 1 February 2019, a month after the beginning of Jair Bolsonaro's only term as president, and ended on 31 January 2023.

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.
