Nahr al-Bared is a Palestinian refugee camp in northern Lebanon, 16 km from the city of Tripoli. Some 30,000 displaced Palestinians and their descendants live in and around the camp, which was named after the river that runs south of the camp. Under the terms of the 1969 Cairo Agreement, the Lebanese Army does not conventionally enter the Palestinian camps, and internal security is provided by Palestinian factions.

Camps are set up by the United Nations Relief and Works Agency (UNRWA) in Jordan, Lebanon, Syria, the West Bank and the Gaza Strip to accommodate Palestinian refugees registered with UNRWA, who fled or were expelled during the 1948 Palestinian expulsion and flight after the 1948 Arab–Israeli War or in the aftermath of the Six-Day War in 1967, and their patrilineal descendants. There are 68 Palestinian refugee camps, 58 official and 10 unofficial, ten of which were established after the Six-Day War while the others were established in 1948 to 1950s.
