General elections were held in Cuba on 3 November 1958. The three major presidential candidates were Carlos Márquez Sterling of the Partido del Pueblo Libre, Ramón Grau of the Partido Auténtico and Andrés Rivero Agüero of the Coalición Progresista Nacional. There was also a minor party candidate on the ballot, Alberto Salas Amaro for the Union Cubana party. Voter turnout was estimated at about 50% of eligible voters. Although Andrés Rivero Agüero won the presidential election with 70% of the vote, he was unable to take office due to the Cuban Revolution. This was the last competitive election in Cuba, the 1940 Constitution of Cuba, the Congress and the Senate of the Cuban Republic, were quickly dismantled shortly thereafter.
