Zuheir Mohsen (Arabic: زهير محسن; 1936 – 25 July 1979) was a Palestinian Politician who was the leader of the Ba'athist As-Sa'iqa faction of the Palestine Liberation Organization (PLO) between 1971 and 1979.

[1] Mohsen was born in Tulkarm, Mandatory Palestine, now in the northern West Bank, where his father was the mukhtar (head of the town).

He subsequently spent time in Qatar, from where he was eventually deported as a result of his political activity, before making his way to Damascus where he helped form as-Sa'iqa.

[4] Journalist Robert Fisk stated that As-Saiqa under Mohsen during the Lebanese Civil War employed its energies against the PLO,[5] seeing in June 1976 "The PLO in open combat within West Beirut against As-Saiqa, who had attacked Arafat's forces on orders from Damascus" [6] As a member of the As-Sa'iqa faction, Mohsen followed the line of Ba'athist ideology, which interpreted the question of Palestine through a pan-nationalist sense which contradicted the PLO's official stance and charter that affirmed the independent existence of Palestinian Arabs as a nation which belongs to a single democratic state that consists of all of former Mandatory Palestine.

Listening to his political and ideological views, one sometimes cannot suppress the feeling that perhaps less has changed in the Arab world than was originally expected",[7] referring to the decline of Pan-Arabism in the aftermath of the Six Day War in 1967.
