Osman Nuri Bey then Pasha (‎; 1832, Tokat, Ottoman Empire – 4 to 5 April 1900, Constantinople, Ottoman Empire), also known as Gazi Osman Pasha, was an Ottoman field marshal who commanded Ottoman forces during the Siege of Plevna in 1877. Although unsuccessful in defending the city, he was awarded the title of "Gazi" ("warrior" or "veteran") for gallantry in holding the city for five months against superior Russo-Romanian forces. In addition to his Adjutancy title, Osman received the Order of the Medjidie and the Imtiyaz Medal for his services to the Empire. He was made "Marshal of the Palace" by the Sultan and the Ottoman military anthem called "Plevna March" was composed for his achievements. The Istanbul suburb of Taşlıtarla was renamed Gaziosmanpaşa in his honour.
