The 1431 papal conclave convened after the death of Pope Martin V and elected as his successor Cardinal Gabriele Condulmer, who took the name Eugene IV. It was the first papal conclave held after the end of the Great Western Schism.

Pope Eugene IV, born Gabriele Condulmer, was head of the Catholic Church and ruler of the Papal States from 11 March 1431 to his death, in February 1447. Condulmer was a Venetian, and a nephew of Pope Gregory XII. In 1431, he was elected pope.
