General elections to the Cortes Generales were held in Spain in October 1836. At stake were all 149 seats in the Congress of Deputies, in order to adopt a new constitution to replace the Royal Statute of 1834. The Cortes eventually enacted the Constitution of 1837.
All male citizens older than 21 had the right to vote.
A majority voting system was used for the election, with 48 multi-member constituencies and 1 single-member constituency. Voting was secret and indirect.
