Map - Baker Island (Baker Island)

Baker Island, formerly known as New Nantucket, is an uninhabited atoll just north of the Equator in the central Pacific Ocean about 3090 km southwest of Honolulu. The island lies almost halfway between Hawaii and Australia. Its nearest neighbor is Howland Island, 42 mi to the north-northwest; both have been claimed as territories of the United States since 1857, though the United Kingdom considered them part of the British Empire between 1897 and 1936.

The island covers 2.1 km2, with 4.8 km of coastline. The climate is equatorial, with little rainfall, constant wind, and strong sunshine. The terrain is low-lying and sandy: a coral island surrounded by a narrow fringing reef with a depressed central area devoid of a lagoon with its highest point being 8 m above sea level.

The island now forms the Baker Island National Wildlife Refuge and is an unincorporated and unorganized territory of the U.S. which vouches for its defense. It is visited annually by the U.S. Fish and Wildlife Service. For statistical purposes, Baker is grouped with the United States Minor Outlying Islands. Baker Island and Howland Island are also the last pieces of land that experience the New Year (furthest behind time zone - UTC−12:00). Baker Island is one of the most remote U.S. equatorial possessions.

A cemetery and rubble from earlier settlements are located near the middle of the west coast, where the boat landing area is located. There are no ports or harbors, with anchorage prohibited offshore. The narrow fringing reef surrounding the island can be a maritime hazard, so there is a day beacon near the old village site. Baker's abandoned World War II runway, 5,463 ft long, is completely covered with vegetation and is unserviceable.

The United States claims an exclusive economic zone of 200 nmi and territorial sea of 12 nmi around Baker Island.

During a 1935–1942 colonization attempt, the island was most likely on Hawaii time, which was then 10.5 hours behind UTC. Since it is uninhabited the island's time zone is unspecified, but it lies within a nautical time zone 12 hours behind UTC (UTC−12:00).
