Legislative elections were held in South Korea on 15 April 2020. All 300 members of the National Assembly were elected, 253 from first-past-the-post constituencies and 47 from proportional party lists. They were the first elections held under a new electoral system.^[1] The two largest parties, the liberal Democratic Party and the conservative United Future Party, set up new satellite parties (also known as bloc parties) to take advantage of the revised electoral system. The reforms also lowered the voting age from 19 to 18.

The Democratic Party and its satellite, the Platform Party, won a landslide victory, taking 180 of the 300 seats (60%) between them.^[2] The Democratic Party alone won 163 seats — the highest number by any party since 1960. This guaranteed the ruling liberal alliance an absolute majority in the legislative chamber, and the three-fifths super-majority required to fast-track its procedures. The conservative alliance between the United Future Party and its satellite Future Korea Party won 103 seats, the worst conservative result since 1960.
