1956 Greek parliamentary election

Parliamentary elections were held in Greece on 19 February 1956. The result was a victory for Konstantinos Karamanlis and his National Radical Union (ERE) by securing the electoral vote despite trailing in the popular vote, due to gerrymandering employed by ERE. It was the first general election in Greece in which women had the right to vote although women had first voted in a by-election in Thessaloniki Prefecture in 1953 in which the first female MP was elected.

Although the Democratic Union, a coalition of centrist parties, received a slim plurality of votes, the conservative governing party, the National Radical Union, won the most seats due to a complex and controversial electoral system enacted by Karamanlis. A "first past the post" system was applied in the rural constituencies where the ERE was expected to gain a plurality, while proportional representation was reserved for the urban constituencies, where the Democratic Union was expected to lead. As a result, the Democratic Union came up 19 seats short of a majority.

The Democratic Union included centrist parties, as the Liberal Democratic Union led by Sophoklis Venizelos and the Liberal Party of Georgios Papandreou, as well as the left-wing EDA, led by Ioannis Passalidis. A few years later, Sophoklis Venizelos and Georgios Papandreou renounced their alliance with EDA, breaking up the Democratic Union.
