Zahir al-Umar al-Zaydani, alternatively spelled Daher al-Omar or Dahir al-Umar (, 1689/90 – 21 or 22 August 1775) was an autonomous Arab ruler of northern Ottoman Palestine in the mid-18th century, while the area was still nominally part of the Ottoman Empire. For much of his reign, starting in the 1730s, his domain mainly consisted of Galilee, with successive headquarters in Tiberias, Arraba, Nazareth, Deir Hanna and finally Acre, in 1746. He fortified Acre, and the city became a center of the cotton trade between Palestine and Europe. In the mid-1760s, he reestablished the port town of Haifa nearby.
