2017 South Korean presidential election

The 19th South Korean presidential election was held on 9 May 2017. The election was called after the impeachment and dismissal of President Park Geun-hye.^[1] The election was held in a single round on a first-past-the-post basis.

The election was originally scheduled to be held on 20 December 2017, but was moved earlier after the decision of the Constitutional Court on 10 March 2017 to uphold the parliament's impeachment of Park Geun-hye.^[2]^[3]^[4]

Opinion polling before April showed the Democratic Party's candidate, Moon Jae-in, runner-up in the 2012 election, as the front-runner and would later go on to win the election.
