The executive branch is headed by the
president. The president is
elected directly by the people, and is the only elected member of the national executive. The president serves for one five-year term; additional terms are not permitted. The President serves a fixed term regardless of the confidence of the National Assembly. However, the President may be impeached by the National Assembly if he or she violates the Constitution or the law, and this provision also applies to the Prime Minister, Ministers, heads of executive ministries, Justices of the Constitutional Court, judges, members of the National Election Commission, the Chairperson and members of the Board of Audit and Inspection, and other public officials as prescribed by law. Once the National Assembly votes in favor of the impeachment the Constitutional Court should either confirm or reject the impeachment resolution, once again reflecting the system of checks and balances between the three branches of the government. The president is
head of state,
head of government and
commander-in-chief of the South Korean armed forces. The president is vested with the power to declare war, and can also propose legislation to the National Assembly. The president can also declare a state of emergency or martial law, subject to the Assembly's subsequent approval. Under the principle of separation of powers, the President may exercise the right to veto a bill as a means of checking the legislature. However, if the National Assembly passes the bill again with the attendance of a majority of its members and the approval of two-thirds of those present, the bill becomes law. The current Constitution does not grant the President the power to dissolve the National Assembly. This safeguard reflects the experience of authoritarian governments under the
First,
Third, and
Fourth Republics. In particular, during the Fourth Republic, the power to dissolve the National Assembly was explicitly granted to the president for the first time in the nation’s constitutional history. On October 17, 1972, President Park Chung-hee issued a “Special Declaration” announcing the Yushin (“Revitalizing Reform”), through which he dissolved the National Assembly and suspended the Constitution. The Yushin Constitution formally adopted a presidential system. However, by granting the president the authority to dissolve the National Assembly—an authority not normally found in presidential systems—it introduced certain elements of a parliamentary system. This provision allowed the president to exercise considerable control over the legislature, expanding the power of the executive branch. Article 59 of the Yushin Constitution stated that “the President may dissolve the National Assembly,” but it did not specify any conditions, procedures, or limits on the president’s responsibility when exercising this power. Since the Constitution at the time did not grant the National Assembly a vote of no confidence in the government, the dissolution power functioned as a unilateral presidential prerogative. This power to dissolve the legislature was maintained under the Constitution of the Fifth Republic. However, following the June Democratic Uprising in 1987 and the subsequent constitutional amendment, the president’s authority to dissolve the National Assembly was removed, restoring the system of checks and balances between the executive and legislative branches. The president is assisted in his or her duties by the
Prime Minister of South Korea as well as the
Presidential Secretariat. The Prime Minister is appointed by the president upon the approval of the National Assembly, and has the power to recommend the appointment or dismissal of the Cabinet ministers. The officeholder is not required to be a member of the National Assembly. The Prime Minister is assisted in his/her duties by the Prime Minister's Office which houses both the
Office for Government Policy Coordination and the Prime Minister's Secretariat (), the former of which is headed by a cabinet-level minister and the latter by a vice minister-level chief of staff. if the president is unable to fulfill his duties, the Prime Minister assumes the president's powers and takes control of the state until the President can once again fulfill his/her duties or until a new president is elected. The
State Council is the highest body and national cabinet for policy deliberation and resolution in the executive branch of the Republic of Korea. The Constitution of the Republic of Korea mandates that the Cabinet be composed of between 15 and 30 members including the Chairperson, and currently the Cabinet includes the President, the Prime Minister, the Vice Prime Minister (the Minister of Strategy and Finance), and the cabinet-level ministers of the 17 ministries. The Constitution designates the President as the chairperson of the Cabinet and the Prime Minister as the vice chairperson. Nevertheless, the Prime Minister frequently holds the meetings without the presence of the President as the meeting can be lawfully held as long as the majority of the Cabinet members are present at the meeting. Also, as many government agencies have moved out of Seoul into other parts of the country since 2013, the need to hold Cabinet meetings without having to convene in one place at the same time has been growing, and therefore the law has been amended to allow Cabinet meetings in a visual teleconference format. Although not the official members of the Cabinet, the
chief presidential secretary (), the Minister of the Office for Government Policy Coordination (), the Minister of Government Legislation (), the Minister of Food and Drug Safety (), the Chairperson of Korea Fair Trade Commission (), the Chairperson of Financial Services Commission (), the
Mayor of Seoul, and other officials designated by law or deemed necessary by the Chairperson of the Cabinet can also attend the Cabinet meetings and speak in front of the Cabinet without the right to vote on the matters discussed in the meetings The Mayor of Seoul, although being the head of a local autonomous region in South Korea and not directly related to the central executive branch, has been allowed to attend the Cabinet meeting considering the special status of Seoul (Special City) and its mayor (the only cabinet-level mayor in Korea). The Cabinet of the Republic of Korea performs somewhat different roles than those of many other nations with similar forms. As the Korean political system is basically a presidential system yet with certain aspects of parliamentary cabinet system combined, the Cabinet of the Republic of Korea also is a combination of both systems. More specifically, the Korean Cabinet performs policy resolutions as well as policy consultations to the President. Reflecting that the Republic of Korea is basically a presidential republic the Cabinet resolutions cannot bind the president's decision, and in this regard, the Korean Cabinet is similar to those advisory counsels in strict presidential republics. At the same time, however, the Constitution of the Republic of Korea specifies in details 17 categories including budgetary and military matters, which necessitates the resolution of the Cabinet in addition to the President's approval, and in this regard the Korean Cabinet is similar to those cabinets in strict parliamentary cabinet systems. The official residence and office of the President of the Republic of Korea is the
Yongsan Presidential Office in Seoul, occupying the building formerly known as the Ministry of National Defense Building. In addition of the Office of the President, the Yongsan Presidential Office building also houses the
Office of National Security and the
Presidential Security Service to assist the President. Formerly, the
Blue House or "Cheongwadae" in
Jongno District was the official residence and office of the President as well as other related agencies, until their transfer to Yongsan in 2022 during the term of President
Yoon Suk-Yeol.
Ministries Currently, 19 ministries exist in the South Korean government. The 19 ministers are appointed by the President and report to the Prime Minister. Also, some ministries have affiliated agencies (listed below), which report both to the Prime Minister and to the minister of the affiliated ministry. Each affiliated agency is headed by a vice-minister-level commissioner except Prosecution Service which is led by a minister-level Prosecutor General. The Minister of Strategy and Finance and the Minister of Education, by law, automatically assume the positions of Deputy Prime Ministers of the Republic of Korea. The respective ministers of the below ministries assume the President's position in the below order, if the President cannot perform his/her duty and the Prime Minister cannot assume the President's position. Also note that the Constitution and the affiliated laws of the Republic of Korea stipulates only so far as the Prime Minister and the 19 ministers as those who can assume the President's position. The commissioner of National Tax Service, a vice-minister-level official by law, is customarily considered to be a minister-level official due to the importance of National Tax Service. For example, the vice-commissioner of the agency will attend meetings where other agencies would send their commissioners, and the commissioner of the agency will attend meetings where minister-level officials convene. •

Board of Audit and Inspection () :: The chairperson of the board, responsible for general administrative oversight, must be approved by the National Assembly to be appointed by the President. Also, although the law provides no explicit regulation regarding the chairperson's rank in the Korean government hierarchy, it is customary to consider the chairperson of the board to enjoy the same rank as a Vice Prime Minister. This is because the law stipulates that the secretary general of the board, the second highest position in the organization, be the rank of minister and therefore the chairperson, directly over the secretary general in the organization, should be at least the rank of Vice Prime Minister in order to be able to control the whole organization without any power clash. •
