The United Nations Support Mission in Libya (UNSMIL) is a United Nations (UN) advanced mission in Libya, created in the aftermath of the Libyan Civil War. UNSMIL is a political mission, not a military mission. The main elements of its mandate defined by the UN include supporting Libyan transitional authorities in "post-conflict efforts", providing mediation in implementing Libyan political agreements, supporting key Libyan institutions and monitoring and reporting on human rights. UNSMIL is led by the UN Department of Political Affairs.

Aims and UN hierarchy
UNSMIL's initial mandate, defined by the UN in 2011, mainly focused on supporting Libyan transitional authorities, including the National Transitional Council of Libya, in "post-conflict efforts" to establish institutions supporting the rule of law.
Under United Nations Security Council Resolution 2009 (UNSCR 2009, in 2011), UNSMIL's mandate was more formally defined in that the United Nations:
Decides to establish a United Nations Support Mission in Libya (UNSMIL), under the leadership of a Special Representative of the Secretary-General for an initial period of three months, and decides further that the mandate of UNSMIL shall be to assist and support Libyan national efforts to:
(a) restore public security and order and promote the rule of law;
(b) undertake inclusive political dialogue, promote national reconciliation, and embark upon the constitution-making and electoral process;
(c) extend state authority, including through strengthening emerging accountable institutions and the restoration of public services;
(d) promote and protect human rights, particularly for those belonging to vulnerable groups, and support transitional justice;
(e) take the immediate steps required to initiate economic recovery; and
(f) coordinate support that may be requested from other multilateral and bilateral actors as appropriate.
In 2016, the mandate was extended to include the provision of mediation in implementing the 2015 Skhirat agreement between the various Libyan transitional institutions that disputed political power. Other elements of UNSMIL's mandate include supporting key Libyan institutions and monitoring and reporting on human rights.
UNSMIL is led by the UN Department of Political Affairs.
UNSMIL's mandate was extended annually and as of 2019 continued to 15 September 2020.
Headquarters
The mission is based in Tunis (Tunisia).

Kobler remained in his functions at UNSMIL for 20 months.
Actions
UNSMIL recorded 48 deaths and 22 injuries in clashes between Libya's political factions in the month of September 2018.
In July 2019, the head of UNSMIL, Ghassan Salamé, proposed a 3-point plan (ceasefire, international meeting to implement the existing arms embargo, and intra-Libyan dialogue) as a new phase in the Libyan peace process, with the aim of resolving the Second Libyan Civil War.
In October 2020, Stephanie Williams undertook wide consultations with Libyan society, including meetings with Libyan mayors from the West, South and East of Libya, as part of the preparations for the Libyan Political Dialogue Forum (LPDF).
In 2022, UNSMIL mediated negotiations that took place in Cairo and eventually in Geneva between the High Counci of State and the House of Representatives that had as their purpose to establish a constitutional basis for elections. The negotiations ultimately ended without the two sides reaching agreement.
The United Kingdom reaffirmed in November 2025 its full support for the United Nations Support Mission in Libya.
