1853 Riograndense legislative election (RRG)

The 1853 Riograndense legislative election was held on September 4, 1853, to elect all members of the Chamber of Deputies and one-third of the Senate. This was the first midterm election in the country's history as it was held in the middle of Antônio de Sousa Netto's first term. The elections resulted in another victory for the Radical Party despite a reduction in its share of the popular vote. Conservatives, which had boycotted elections since the establishment of the Second Republic, were divided between the Party of Order, which had accepted the 1851 Constitution, and the reactionary Conservative Party that called for a return to the First Republic.

The election to the Chamber of Deputies remained the same as its members were chosen via firs-past-the-post from single-member constituencies. The 5 seats of in the Senate that were up to re-election were chosen via single non-transferable voting from a nationwide electoral list. Each senator and member of the Chamber was elected on a joint ticket with a substitute, allowing for party leaders who were candidates for both houses to choose their eventual seat.
