The National Election Commission (Korean: 중앙선거관리위원회; Hanja: 中央選擧管理委員會; RR: Jungang Seongeo Gwalliwiwonhoe; NEC) is an independent constitutional institution in South Korea, established to manage free and fair elections, national referendums and other administrative affairs concerning political parties and funds.

[1] This highly independent status of NEC reflects national will to overcome past histories such as election rigging of South Korea in 1960.

During the period of the 2024 South Korean martial law, troops were sent to raid the commission headquarters.

No member of the commission shall be expelled from office except by impeachment or a sentence of imprisonment without prison labor or heavier punishment.

The commission also manages entrusted elections for heads of the Agricultural, Fisheries, Livestock and Forestry Cooperatives and for candidates of presidents of National Universities.
