Bithnah Fort is a traditional double story rock, coral and mudbrick fortification located in the Wadi Ham, near the village of Bithnah in Fujairah, United Arab Emirates. The fort has played a significant role in the history of the Emirates, particularly in the emergence of Fujairah as an independent emirate in the early 20th century. With a controlling position overlooking the Wadi Ham, the fort replaced an Iron Age fortification.

The Emirate of Fujairah is one of the seven emirates that make up the United Arab Emirates, the only one of the seven with a coastline solely on the Gulf of Oman and none on the Persian Gulf. Its capital is Fujairah.
