Parliamentary elections were held in Brazil on 3 October 1990, the first held under the 1988 constitution. The Brazilian Democratic Movement Party emerged as the largest party, winning 108 of the 502 seats in the Chamber of Deputies and 8 of the 31 seats in the Senate. Allies of President Fernando Collor de Mello, elected the previous year, won a majority in both houses of Congress. However in September 1992, Collor's presidency came to an abrupt end when he resigned in a failed attempt to avoid impeachment on corruption charges.
