Omar Abdel-Rahman, Egyptian terrorist
Sheikh Omar Abdel-Rahman (Arabic: عمر عبد الرحمن), (ʾUmar ʾAbd ar-Raḥmān; 3 May 1938 – 18 February 2017), commonly known in the United States as "The Blind Sheikh", was a blind Egyptian Islamist militant who served a life sentence at the Federal Medical Center, Butner near Butner, North Carolina, United States. Formerly a resident of New York City, Abdel-Rahman and nine others were convicted of seditious conspiracy. His prosecution grew out of investigations of the 1993 World Trade Center bombing.

Abdel-Rahman was the leader of Al-Jama'a al-Islamiyya (also known as "The Islamic Group"), a militant Islamist movement in Egypt that is considered a terrorist organization by the United States and Egyptian governments. The group was responsible for many acts of violence, including the November 1997 Luxor massacre, in which 58 foreign tourists and four Egyptians were killed.
