Binyam Ahmed Mohamed (Arabic: بنيام محمد‎) (also described as Benjamin Mohammed, Benyam (Ahmed) Mohammed and Benyam Mohammed al-Habashi) (born 24 July 1978) is an Ethiopian national who was detained in Guantanamo Bay prison between 2004 and 2009. He was captured and transported under the US extraordinary rendition program. After charges against him were dropped, he was eventually released and arrived in the United Kingdom on 23 February 2009. Mohamed admitted while he was detained that he trained in the Al-Qaeda terrorist training camp Al Farouq, but has since claimed that the evidence against him was obtained using torture.

Binyam Mohamed has claimed to have been tortured in US custody, and tortured while in nominally Moroccan custody. He was alleged to have played a role in what American counter-terrorism analysts characterized as a "dirty bomb plot" with Jose Padilla.

In 1994, Mohamed sought asylum in the United Kingdom.
