The Battle of Tripoli (Arabic: مَعْرَكَة طَرَابُلُس, romanized: Maʿrakat Ṭarābulus) was a major battle during the middle of the Lebanese Civil War in late 1983. It took place in the northern coastal city of Tripoli between pro-Syrian Palestinian militant factions and the Palestine Liberation Organization (PLO) led by Yassir Arafat. It resulted in the withdrawal of PLO and mostly ended their involvement in the war.
