The Vilayet of Trebizond or Trabzon (, ; ) was a first-level administrative division ("vilayet") in the north-eastern part of the Ottoman Empire, corresponding to the area along the eastern Black Sea coastline and the interior highland region of the Pontic Alps.

The accuracy of the population figures ranges from "approximate" to "merely conjectural" depending on the region from which they were gathered. After the Russian-Turkish  War of 1877–1878, the sanjak of Lazistan was established. Rize became the center of the district due to the cession of Batumi, the former centre of the sanjak, to Russia with kaza of Artvin. The salname of the year 1344h/1904-1905 mentioned several Armenian pharmacists. The Vilayet also counted with a considerable Greek population. During World War I eastern half of vilayet (Kazas of Görele, Vakfıkebir, Akçaabat, Trabzon, Of and Maçka with sanjaks of Lazistan and Gümüşhane) was occupied by Russian troops by summer 1916. It was retaken by Ottomans in 1918. Demographics. The Sanjak of Trabzon had a Muslim  majority since the 16th century.
