At Stake in this Election:
- The Office of the President of the Republic of Korea.
- Chief of State: President MOON Jae-in (since 10 May 2017)
- Head of Government: President MOON Jae-in (since 10 May 2017)
- Assembly: The National Assembly of the Republic of Korea (Daehanminguk Gukhoe or Kuk Hoe / 대한민국 국회 大韓民國 國會) is a unicameral legislature consisting of 300 seats.
- The President of the Republic of Korea is elected to a five-year term using a single round plurality voting system and is limited to serving a single term. 
- The National Assembly (Kuk Hoe) is a unicameral institution consisting of 300 seats, of which 253 are directly elected in single-seat constituencies by simple majority vote. The remaining 47 seats are elected in a single national constituency using a system of proportional representation.* All members of the National Assembly serve four-year terms. 
* The method of seat distribution for the 47 members determined by proportional representation was amended following the passage of an electoral reform bill on 27 December 2019.  Thirty of those seats are now determined using a new compensatory system, while the remaining seats continue to be decided by the parallel voting systems that had existed prior to the reform.  The reform is expected to boost the presence of minor parties in the National Assembly and has consequently attracted backlash from main parties. 
- The last elections in the Republic of Korea were held on 15 April 2020 for the National Assembly (Kuk Hoe), while the last presidential elections were held on 9 May 2017.
