The Roanoke Colony, also known as the Lost Colony, was established on Roanoke Island in what is today's Dare County, North Carolina, United States. It was a late 16th-century attempt by Queen Elizabeth I to establish a permanent English settlement. The colony was founded by Sir Walter Raleigh. The colonists disappeared during the Anglo-Spanish War, three years after the last shipment of supplies from England.
