The Connecticut Indian Land Claims Settlement was an Indian Land Claims Settlement passed by the United States Congress in 1983. The settlement act ended a lawsuit by the Mashantucket Pequot Tribe to recover 800 acres of their 1666 reservation in Ledyard, Connecticut. The state sold this property in 1855 without gaining ratification by the Senate. In a federal land claims suit, the Mashantucket Pequot charged that the sale was in violation of the Nonintercourse Act that regulates commerce between Native Americans and non-Indians.
