Abdullah ibn-Mohammed al-Khalifa or Abdullah al-Taashi or Abdallah al-Khalifa, also known as "The Khalifa" (Arabic: c. عبدالله بن سيد محمد الخليفة; 1846 – 25 November 1899) was a Sudanese Ansar ruler who was one of the principal followers of Muhammad Ahmad. Ahmad claimed to be the Mahdi, building up a large following. After Ahmad's death, Abdullah ibn-Mohammed took over the movement, adopting the title of Khalifah al-Mahdi (usually rendered as "Khalifa"). He attempted to create a kingdom, which led to widespread discontent, and his eventual defeat and death at the hands of the British and Egyptians.
