Asar-i Tevfik (Ottoman Turkish: God's Favor) was an ironclad warship of the Ottoman Navy built in the 1860s, the only member of her class. She was built as part of a major expansion program for the Ottoman fleet in the 1860s following the Crimean War. Asar-i Tevfik was a 4,600-metric-ton (4,500-long-ton; 5,100-short-ton) barbette ship armed with a main battery of eight 220-millimeter (8.7 in) guns in a central battery. In 1903–1906, the ship was extensively rebuilt in Germany and a new battery of 150 mm (5.9 in) and 120 mm (4.7 in) quick-firing guns replaced the older weapons.
