The United Nations Mission in Sierra Leone (UNAMSIL) was a United Nations peacekeeping operation in Sierra Leone from 1999 to 2006. It was created by the United Nations Security Council in October 1999 to help with the implementation of the Lomé Peace Accord, an agreement intended to end the Sierra Leonean civil war. UNAMSIL expanded in size several times in 2000 and 2001. It concluded its mandate at the end of 2005, the Security Council having declared that its mission was complete.

It superseded the United Nations Observer Mission in Liberia (UNOMIL). As of July 2016, 1,240 U.N. military and 606 police personnel remained on the ground, but were there only in case of emergency.

The United Kingdom began a military intervention in Sierra Leone on 7 May 2000 under the codename Operation Palliser. Although small numbers of British personnel had been deployed previously, Palliser was the first large-scale intervention by British forces in the Sierra Leone Civil War. In early May 2000, the Revolutionary United Front (RUF)—one of the main parties to the civil war—advanced on the country's capital, Freetown, prompting the British government to dispatch an "operational reconnaissance and liaison team" (ORLT) to prepare to evacuate foreign citizens. On 6 May, the RUF blocked the road connecting Freetown to the country's main airport, Lungi. The next day, British soldiers began to secure the airport and other areas essential to an evacuation. The majority of those who wished to leave were evacuated within the first two days of the operation, but many chose to stay following the arrival of British forces.
The United Nations Observer Mission in Sierra Leone (UNOMSIL) was a United Nations peacekeeping operation in Sierra Leone from 1998 to 1999 that was established with the passage of United Nations Security Council Resolution 1181.

The mission was terminated in October 1999, when the Security Council authorized deployment of a new, and significantly larger peacekeeping operation, the Nations Mission in Sierra Leone (UNAMSIL).
