Foxwoods Resort Casino is a hotel and casino complex owned and operated by the Mashantucket Pequot Tribal Nation on their reservation located in Ledyard, Connecticut. Including six casinos, the resort covers an area of 9,000,000 sq ft (840,000 m2). The casinos have more than 250 gaming tables for blackjack, craps, roulette, and poker, and have more than 5,500 slot machines. The casinos also have several restaurants, among them a Hard Rock Cafe. It has been developed since changes in state and federal laws in the late 20th century enabled Native American gaming on the sovereign reservations of federally recognized tribes.

The Mashantucket Pequot Tribal Nation is a federally recognized American Indian tribe in the state of Connecticut. They are descended from the Pequot people, an Algonquian-language tribe that dominated the southern New England coastal areas, and they own and operate Foxwoods Resort Casino within their reservation in Ledyard, Connecticut. As of 2018, Foxwoods Resort Casino is one of the largest casinos in the world in terms of square footage, casino floor size, and number of slot machines, and it was one of the most economically successful in the United States until 2007, but it became deeply in debt by 2012 due to its expansion and changing conditions.
