The Sanjak of Acre (Turkish: Akka Sancağı) was a prefecture (sanjak) of the Ottoman Empire, located in modern-day northern Israel. The city of Acre was the Sanjak's capital. Acre was captured by the Ottoman Sultan Selim I in 1517, but the city fell into disuse soon thereafter and was governed under the Sanjak of Safad. Acre was the center of the Nahiya of Acre, a subdistrict of the sanjak, which also included the villages of Buqei'a, Ein Tiriah, Julis, Kafr Yasif, Kabul and Shefa-'Amr. Acre was the center of a major economic boom under the leadership of Zahir al-Umar during the late 18th century.
