The United Nations Interim Force in Lebanon (Arabic: قوة الأمم المتحدة المؤقتة في لبنان; Hebrew: כוח האו"ם הזמני בלבנון), or UNIFIL (Arabic: يونيفيل; Hebrew: יוניפי״ל) is a United Nations peacekeeping mission established on 19 March 1978 by United Nations Security Council Resolutions 425 and 426, and resolution 1701 in 2006 to restore peace and security along the Israel-Lebanon border.
UNIFIL was established as a result of the 1978 Israeli invasion of Lebanon at a time of Palestinian insurgency in South Lebanon and the Lebanese Civil War. The UNIFIL mandate had to be adjusted due to the Israeli invasion of Lebanon in 1982 and after the Israeli withdrawal from Lebanon in 2000. Following the 2006 Lebanon War, the United Nations Security Council enhanced UNIFIL and added additional tasks to the mandate, such as aiding displaced persons.
UNIFIL's mandate is renewed annually by the United Nations Security Council; it was most recently extended on 28 August 2025 with the passing of UNSCR 2790 which set out the final extension of the mission's mandate until 31 December 2026, with its drawdown and withdrawal to then take place throughout 2027. The UNSC called for the full implementation of Resolution 1701, including full respect for the Blue Line and full cessation of hostilities.
As of 2026 UNIFIL is composed of 7,478 personnel from 47 nations, tasked with monitoring the cessation of hostilities and helping ensure humanitarian access to the civilian population. Its funding is approved on an annual basis by the General Assembly. It has a budget of $553 million for the fiscal year 2025 to 2026.
