Parliamentary elections were held in the Empire of Brazil on 1 December 1884 to elect members of the 19th legislature of the Chamber of Deputies. These were the second direct elections held in the country after the Saraiva Law was enacted (Law No. 3,029 of 9 January 1881). The Liberal Party won 67 seats, the Conservative Party won 55, and the Republican Party won 3. The chamber was later dissolved on 26 September 1885. The province of Pará was redivided into 6 districts.[1]
