Abd al-Majid Nimer Zaghmout (died 15 February 2000) was a Palestinian national imprisoned in Syria who was described by Amnesty International as "possibly the longest-serving arbitrarily detained political prisoner in the Middle East". At his death, he was arguably the longest-serving political prisoner in the world.
He was arrested in 1966 and charged with the politically motivated murder of the Palestinian guerrilla leader Yusuf 'Urabi. He denied the charges and alleged he had been tortured for 46 days after his arrest to force him to confess.
After a trial described in some quarters as "unfair"[web.amnesty.org/library/Index/ENGMDE240201998?open&of=ENG-348] he was sentenced to death by a military court.
He died of cancer in a military hospital on 15 February 2000.
