The South Lebanon conflict was an armed conflict that took place in Israeli-occupied southern Lebanon from 1982 or 1985 until Israel's withdrawal in 2000. Hezbollah, along with other Shia Muslim and left-wing guerrillas, fought against Israel and its ally, the Catholic Christian-dominated South Lebanon Army (SLA). The SLA was supported militarily and logistically by the Israel Defense Forces (IDF) and operated under the jurisdiction of the Israeli-backed South Lebanon provisional administration, which succeeded the earlier Israeli-backed Free Lebanon State. Israel officially names the conflict the Security Zone in Lebanon Campaign and deems it to have begun on 30 September 1982, after the end of its "Operation Peace for Galilee". It can also be seen as an extension of the Lebanese Civil War (1975–1990).

Israel invaded Lebanon in 1978 and in 1982, to end the Palestinian insurgency in South Lebanon and support Lebanese Maronite Christians in the Lebanese Civil War. The 1982 invasion resulted in the Palestine Liberation Organization (PLO) leaving Lebanon and marked the beginning of Israeli occupation. Militant groups began attacking Israeli forces in southern Lebanon in September 1982. Amid rising casualties from guerrilla attacks, the IDF retreated south of the Awali river on 3 September 1983. The IDF began a phased withdrawal from Lebanon in February 1985. It withdrew to a "security zone" along the border on 29 April, and most IDF troops withdrew from the "security zone" on 10 June. A small number of IDF soldiers remained in the zone to support the SLA. Throughout its existence, there were about 1,500 IDF and 2,500 SLA troops in the "security zone" at any given time.

The occupation led to the creation of the Shia Islamist paramilitary group Hezbollah. It began waging a guerrilla war against the IDF and the SLA, with support from Iran and Syria. The IDF and the SLA engaged in counterinsurgency, but Israel had no long-term strategy. With Hezbollah increasingly targeting the Galilee with rockets, the official purpose of the Security Zone—to protect Israel's northern communities—seemed contradictory. Hezbollah also excelled at psychological warfare, often recording their attacks on Israeli troops. Israel launched two major operations in southern Lebanon during the 1990s: Operation Accountability in 1993 and Operation Grapes of Wrath in 1996. Following the 1997 Israeli helicopter disaster, the Israeli public began to seriously question whether the occupation of southern Lebanon was worth maintaining. The Four Mothers movement rose to the forefront of the public discourse, and played a leading role in swaying the public in favour of a complete withdrawal.

The Israeli government hoped that a withdrawal from the security zone could be carried out in the context of a wider agreement with Syria and, by extension, Lebanon. Talks with Syria failed. By 2000, following up on his promise during the 1999 Israeli general election, the new Israeli prime minister Ehud Barak unilaterally withdrew Israeli forces from southern Lebanon on 25 May 2000, in accordance with United Nations Security Council Resolution 425 of 1978. Israel's withdrawal resulted in the immediate and total collapse of the SLA, with many of its members escaping to Israel. The Lebanese government and Hezbollah consider the withdrawal incomplete until Israel withdraws from Shebaa Farms. In 2020, Israel recognized the conflict as an IDF military campaign.
