General elections were held in Portugal on 28 April 1918, following a coup by Sidónio Pais in December 1917.^[1] The elections were boycotted by the Democratic Party, the Evolutionist Party and the Republican Union, who had won over 90% of the seats in the 1915 elections.^[2]

Although they included the first direct vote election for the position of President, Pais was the only candidate and the vote was uncontested.^[3] In the parliamentary elections the result was a victory for the National Republican Party, which won 108 of the 155 seats in the House of Representatives and 32 of the 73 seats in the indirectly elected Senate.^[4][5]
