Ahmet Tevfik Pasha (Ottoman Turkish: احمد توفیق پاشا; 11 February 1843 – 8 October 1936), later Ahmet Tevfik Okday after the Turkish Surname Law of 1934, was an Ottoman diplomat and statesman of Crimean Tatar origin. He was the last grand vizier of the Ottoman Empire.
Tevfik Pasha had the misfortune of his terms as Grand Vizier coinciding with disastrous moments in late Ottoman history; his first term with the deposition of Abdul Hamid II, the second term with the occupation of Istanbul after World War I, and the third term with the abolition of the Sultanate. In addition to serving as Grand Vizier, Ahmet Tevfik was also a diplomat, a member of the Ottoman Senate, and long time Minister of Foreign Affairs.
