Sheikh Omar Abdel-Rahman (, Umar 'Abdu r-Raḥman; 3 May 1938 – 18 February 2017), commonly known in the United States as "The Blind Sheikh", was a blind Egyptian Muslim leader 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.
