The United Nations Mission in the Democratic Republic of Congo (MONUC) was the name of the United Nations peacekeeping force in the the Democratic Republic of the Congo (DRC).which was established by the United Nations Security Council in resolutions 1279 (1999) and 1291 (2000) of the United Nations Security Council to monitor the peace process of the Second Congo War, though much of its focus subsequently turned to the Ituri conflict, the Kivu conflict and the Dongo conflict.

The initial UN presence in the Democratic Republic of the Congo, before the passing of Resolution 1291, was a force of military observers to observe and report on the compliance on factions with the peace accords, a deployment authorised by the earlier Resolution 1258 (1999).

n accordance with Security Council resolution 1925 of 28 May 2010, MONUC was renamed as of 1 July the United Nations Organization Stabilization Mission in the Democratic Republic of the Congo (MONUSCO) to reflect the new phase reached in the country.
