Al Maryah Island, formerly known as Sowwah Island, is a natural island located northeast of Abu Dhabi, the capital of the United Arab Emirates. It is named for a famous oasis region in Abu Dhabi, Al Mariyah, which in turn is named after the species of Arabian deer – Al Mariyah – which live there.
Al Maryah Island covers approximately 114 hectares and is currently being developed by Mubadala to be a new city center. It is one of the largest construction sites in Abu Dhabi.
In March of 2023, the Umm Al Quwain Department of Tourism and Archaeology announced the discovery of the oldest known pearling town in the Persian Gulf, on Siniyah Island.
