1857 Mexican general election
General elections were held in Mexico in September 1857. They were the first to be held under the February 1857 constitution, which introduced direct elections for the presidency, abolished the Senate, and introduced universal male suffrage for citizens aged 18 or 20, as long as they had an "honest mode of living".
Incumbent president Ignacio Comonfort was re-elected with 93% of the vote, defeating Miguel Lerdo de Tejada.
