PSF) (Arabic: جبهة النضال الشعبي الفلسطيني, Jabhet Al-Nedal Al-Sha'abi Al-Falestini) is a Palestinian political party.

[2] PPSF holds a seat on the Palestine Liberation Organization (PLO) executive council, though it is generally considered to have a limited influence over Palestinian politics.

In 1969, the organization attacked civilian Israeli and Greek passengers in Athens Airport in 1969 which resulted in 14 injures and one dead child.

Members of the PPSF were mentioned as possible suspects in the 1988 Lockerbie Bombing, believed to have been orchestrated by the Libyan regime, but Samir Ghawshah denied the charges.

[6] In 1991, PPSF was allowed to rejoin the PLO after accepting United Nations Security Council Resolution 242 and the concept of negotiations with Israel.
