The Ministry of Foreign Affairs of the Republic of Indonesia (MoFA), commonly referred to as the Foreign Affairs Ministry (Indonesian: Kementerian Luar Negeri Republik Indonesia abbreviated "Kemlu"), is a government ministry responsible for the country's foreign politics and diplomacy. The ministry was formerly known as the Department of Foreign Affairs (Departemen Luar Negeri Republik Indonesia, better known as Deplu). The name changed due to the new law about State Ministry of 2008 (UU 39/2008).

Ministry of Foreign Affairs is one of the ministries (along with Ministry of Defense and Ministry Home Affairs) that is mentioned in the Constitution of Indonesia, so the president has no authority to dissolve this ministry, compared to other ministries that are not mentioned in the Constitution of Indonesia.

In the case that both of the president and the vice president can no longer serve at the same time, the line of succession falls to the minister of foreign affairs, minister of home affairs and minister of defence concurrently until the succeeding President and Vice President are elected by the People's Consultative Assembly within thirty days.
