Legislative elections were held in South Korea on 13 April 2000. Opinion polls suggested that the ruling Democratic Party would win the most seats, but the result was a victory for the conservative Grand National Party (GNP), which won 133 of the 273 seats in the National Assembly. The United Liberal Democrats (ULD) lost two-thirds of their seats due to GNP's victory in Gyeongsangbuk-do, Gangwon-do (South Korea), and also fewer local votes in Chungcheong. With no party winning a majority, the 16th parliament was the first Hung Parliament in South Korean history.
