Isla de los Estados (Dutch: Stateneiland) is an Argentine island that lies 29 km off the eastern extremity of the Argentine portion of Tierra del Fuego, from which it is separated by the Le Maire Strait. It was named for the Netherlands States-General, and its original Dutch name was identical to that of the New York borough of Staten Island.
The island is administratively part of the Argentinian province of Tierra del Fuego, and of the department and city of Ushuaia. It has been declared an "Ecological, Historic, and Tourist Provincial Reserve" ("Reserva provincial ecológica, histórica y turística"), with access limited to tours from Ushuaia. The only settlement is the Puerto Parry Naval Station, located in a deep and narrow fjord on the northern coast of the island. The naval station, created in 1978, is manned by a team of four marines on a 45-day rotation, in charge of monitoring environmental conservation, ship movement, and also to provide emergency assistance.
