1963 South Korean legislative election

Legislative elections were held in South Korea on 26 November 1963. They were the first held after the 1961 coup and subsequent approval of a new constitution the previous December, which inaugurated the Third Republic. All candidates had to run under the banner of a political party.
The result was a victory for the Democratic Republican Party of coup leader Park Chung Hee, which won 110 of the 175 seats in the National Assembly. Voter turnout was 72.1%.

Electoral system

The unicameral National Assembly was elected by parallel voting, with 131 legislators elected in single-member constituencies and 44 allocated via a modified formula on the national level, excluding parties that did not win more than three seats or more than 5% of the valid vote. If the percentage of votes for the first-placed party was over 50%, the national seats would be allocated in proportion to vote share, with the first-placed party being limited to two-thirds of the available national seats. When the number of votes of the top party was less than 50%, half of the seats in the national constituency were automatically allocated to the first-placed party, and the process repeated for the remaining parties until all remaining seats were allocated.
