Presidential elections were held in Portugal on 16 December 1918. Following Portugal's 1911 constitution, the Congress of the Republic must elect the president in Lisbon instead of the Portuguese people.[1]
The election was held two days after the assassination of the Portuguese president Sidónio Pais on 14 December 1918. There were a total of four candidates. At the first ballot quorum wasn't reached, so the election was repeated, this time with the necessary members present. National RepublicanJoão do Canto e Castro won against his opponents and he was elected as the new President of Portugal succeeding the late Sidónio Pais.
