Count Iosif Vladimirovich Romeyko-Gurko, also known as Joseph or Ossip Gourko, was a prominent Russian field marshal during the Russo-Turkish War (1877–1878).

The Russo-Turkish War was a conflict between the Ottoman Empire and a coalition led by the Russian Empire which included Bulgaria, Romania, Serbia, and Montenegro. Fought in the Balkans and in the Caucasus, it originated in emerging 19th-century Balkan nationalism. Additional factors included the Russian goals of recovering territorial losses endured during the Crimean War of 1853–1856, re-establishing itself in the Black Sea and supporting the political movement attempting to free Balkan nations from the Ottoman Empire.
