The Al Ali is a tribe of the Arabian Peninsula, notably in the United Arab Emirates. The tribe originally settled the island of Siniyah off Umm Al Quwain, later moving to the mainland and building a fort and defensive wall there in the late 1700s, founding the Emirate of Umm Al Quwain. The emirate consists in the main of the coastal city of Umm Al Quwain and the inland oasis town of Falaj Al Mualla, some 30 km from the coast.
