Mehmed V Reşâd (Ottoman Turkish: محمد خامس, romanized: Meḥmed-i ẖâmis; Turkish: V. Mehmed or Mehmed Reşad; 2 November 1844 – 3 July 1918) reigned as the 35th and penultimate Ottoman Sultan (r. 1909–1918). He was the son of Sultan Abdulmejid I. He succeeded his half-brother Abdul Hamid II after the 31 March Incident. He was succeeded by his half-brother Mehmed VI.

His nine-year reign was marked by the cession of the Empire's North African territories and the Dodecanese Islands, including Rhodes, in the Italo-Turkish War, the traumatic loss of almost all of the Empire's European territories west of Constantinople (now Istanbul) in the First Balkan War, and the entry of the Ottoman Empire into World War I in 1914, which would ultimately lead to the Empire's end.
