Umm Al Quwain Fort, also known as the Al Ali Fort, is located in the city of Umm Al Quwain in the United Arab Emirates (UAE). It was the seat of the rulers of Umm Al Quwain and the centre of government in the emirate until 1969. It was used as a police station before the fort was restored and opened to the public in 2000 by Sheikh Rashid Bin Ahmed Al Mualla, the Ruler of Umm Al Quwain at the time.
Today it houses the Umm Al Quwain National Museum. Exhibits include artefacts from the important archeological site of Ed-Dur.
