Dibba is a coastal town located at the northeastern tip of the UAE/Oman peninsula on the Gulf of Oman. Dibba consists of three villages:

• Dibba Bayah, ruled by the Sultanate of Oman
• Dibba Muhallab, ruled by the Emirate of Fujairah
• Hisn Dibba, ruled by the Emirate of Sharjah

Dibba was the site of the Ridda War, or War of Apostasy c. 633 AD. The plains of Dibba contain a large cemetary, which, according to tradition, represents the defeated apostates of Dibba killed by the caliph Abu Bakr.
