Atef Bseiso (, 23 August 1948 – 8 June 1992) was the Palestine Liberation Organization's (PLO) liaison officer with foreign intelligence agencies. He was assassinated in Paris in 1992. Several theories exist regarding the reason for his murder. According to one, alleging he played a role in the 1972 Munich Olympics massacre, his execution was part of the Wrath of God Operation. Others argue it was an Israeli operation aiming to disrupt relations of the PLO with Western intelligence agencies. The PLO denied Bseiso had any connection to the Munich operation.
