# Gangbuk A

Gangbuk A (Korean: 강북구 갑) is a constituency of the National Assembly of South Korea. The constituency consists of parts of Gangbuk District, Seoul. As of 2024, 132,265 eligible voters were registered in the constituency. The constituency was created in 1996 after being reorganized from the Dobong C constituency.

## History

Since its establishment, Gangbuk A has more often elected members of centre-left, liberal parties to represent the constituency. Kim Won-gil of the centrist-liberal National Congress for New Politics was the first member to represent the constituency. Kim won re-election in 2000 as a member of the centre-left Millennium Democratic Party, but joined the conservative Grand National Party ahead of the 2002 South Korean presidential election. Kim ran as the Grand National Party's nominee for Gangbuk A in the 2004 election, but was defeated by Oh Yeong-sik of the liberal Uri Party by more than ten points. In the following election, Oh was defeated by Cheong Yang-seog of the Grand National Party. However, in the 2012 election, Oh won back the seat in a rematch against Cheong. Cheong won back the seat in 2016 as a member of the conservative Saenuri Party, securing 39.52% of the vote and narrowly beating out Democratic challenger Cheon Jun-ho. Cheong lost to Cheon Jun-ho in the following election, who won in a landslide with 57.75% of the vote. Cheon won re-election in 2024 in a one-on-one battle against Jun Sang-bum of the conservative People Power Party.

## Boundaries

The constituency encompasses the neighborhoods of Beon 1-dong, Beon 2-dong, Ui-dong, Insu-dong, and Suyu-dong.
