UN Mission of Observers in Prevlaka (UNMOP) was established on 15 January 1996 in Security Council Resolution 1038 as a peacekeeping mission to monitor the demilitarization of the disputed Prevlaka peninsula by carrying out daily foot and vehicle patrols on both sides of the border between Croatia and FR Yugoslavia (specifically, its federal unit Montenegro).

Countries providing support for this mission included Finland, Argentina, Belgium, Indonesia, Denmark, Kenya, Poland, Portugal, Sweden, Norway, Ireland, New Zealand and the USA.

It was disbanded on 15 December 2002, the date set by the UN Security Council.
