The Eyalet of the Islands of the White Sea (Ottoman Turkish: ایالت جزایر بحر سفید, romanized: Eyālet-i Cezāyir-i Baḥr-i Sefīd, lit. 'Eyalet of the Islands of the White Sea') was a first-level province (eyalet) of the Ottoman Empire. From its inception until the Tanzimat reforms of the mid-19th century, it was under the personal control of the Kapudan Pasha, the commander-in-chief of the Ottoman Navy.
