Mohegan Sun is an American casino, owned and operated by the Mohegan Tribe on 240 acres (97 ha) of their reservation, along the banks of the Thames River in Uncasville, Connecticut.

In 2012, Mohegan entered into a joint venture and management arrangement with Resorts Casino Hotel in Atlantic City, becoming the first Native American-owned casino in Atlantic City and the first time a Native American tribe had taken ownership of a commercial property in the United States.
