Chung Doo-un

Chung Doo-un (, 6 March 1957 – 16 July 2019) was a South Korean politician who was Vice-Mayor of Seoul from 2000 to 2003.

Chung, along with Chu ho-young and Park Heong-joon, was a close associate of President Lee Myung-bak but later became critical of him and the leadership of the Grand National Party after Lee's election. On 26 August 2011, he described Lee Myung-bak's fair society governance as a failure due to the prime minister-led surveillance against civilians in 2010.

The Minjoo Party's Kim Young-ho took his seat in the National Assembly at the 20th general election, held on 13 April 2016.

Death
Chung committed suicide, aged 62, in a park in Seoul on 16 July 2019.
