The Line Islands, Teraina Islands or Equatorial Islands are a chain of atolls and coral islands. Kingman Reef is largely submerged and Filippo Reef is shown on some maps, although its existence is doubted. The islands were formed by volcanic activity and are located in the central Pacific Ocean, south of the Hawaiian Islands. The 11 islands stretch for 2,350 kilometres in a northwest–southeast direction, making it one of the longest island chains of the world. Eight of the islands form part of Kiribati, while the remaining three are United States territories grouped with the United States Minor Outlying Islands. Only Kiritimati and Tabuaeran atolls and Teraina Island have a permanent population.

Caroline Island, is the easternmost of the uninhabited coral atolls which comprise the southern Line Islands in the central Pacific Ocean of Kiribati.
Filippo Reef is a reef that is asserted to be in the Pacific Ocean at 05°30′S 151°50′W, 450 kilometres (280 mi) east of Starbuck Island in the Line Islands. The reef was reported by the master of the Italian barque Filippo as having been seen on 28 June 1886. From an unidentified report of breakers dated 1926, it was estimated to have a water depth of only 0.6 to 0.9 metres, and appeared to be about 1.6 kilometres (1.0 mi) long northwest to southeast, and less in width.

Flint Island is an uninhabited coral island in the central Pacific Ocean, part of the Southern Line Islands under the jurisdiction of Kiribati. In 2014 the Kiribati government established a twelve-nautical-mile exclusion zone around each of the southern Line Islands.
Jarvis Island is an uninhabited 1 3⁄4-square-mile (4.5 km2) coral island located in the South Pacific Ocean, about halfway between Hawaii and the Cook Islands. It is an unincorporated, unorganized territory of the United States, administered by the United States Fish and Wildlife Service of the United States Department of the Interior as part of the National Wildlife Refuge system. Unlike most coral atolls, the lagoon on Jarvis is wholly dry.

Kingman Reef is a largely submerged, uninhabited triangular-shaped reef, 9.0 nautical miles east-west and 4.5 nmi (8 km) north-south, in the North Pacific Ocean, roughly halfway between the Hawaiian Islands and American Samoa. It has an area of 3 hectares and is one of the unincorporated territories of the United States in Oceania.

Kiritimati or Christmas Island is a Pacific Ocean coral atoll in the northern Line Islands. It is part of the Republic of Kiribati. Its Gilbertese name is the rendition of the English word "Christmas" according to its phonology, in which the combination ti is pronounced s, and the name is thus pronounced.

Malden Island, sometimes called Independence Island in the nineteenth century, is a low, arid, uninhabited atoll in the central Pacific Ocean, about 39 km2 (15 sq mi) in area. It is one of the Line Islands belonging to the Republic of Kiribati. The lagoon is entirely enclosed by land, though it is connected to the sea by underground channels, and is quite salty.

Palmyra Atoll, also referred to as Palmyra Island, is one of the Northern Line Islands (southeast of Kingman Reef and north of Kiribati. It is located almost due south of the Hawaiian Islands, roughly one-third of the way between Hawaii and American Samoa. The nearest continent is almost 3,355 miles to the northeast. The atoll is 4.6 sq mi, lying in the equatorial Northern Pacific Ocean. Its 9 miles of coastline has one anchorage known as West Lagoon.

Starbuck Island is an uninhabited coral island in the central Pacific, and is part of the Central Line Islands of Kiribati. Former names include "Barren Island", "Coral Queen Island", "Hero Island", "Low Island", and "Starve Island".

Tabuaeran, known in English as Fanning Island, is an atoll that is part of the Line Islands of the central Pacific Ocean and part of Kiribati. The land area is 33.73 square kilometres, and the population in 2015 was 2,315. The maximum elevation is about 3 m (10 ft) above high tide.

Teraina is a coral atoll in the central Pacific Ocean and part of the Northern Line Islands which belong to Kiribati. Obsolete names of Teraina are New Marquesas, Prospect Island, and New York Island. The island is located approximately 4.71° North latitude and 160.76° West longitude. Teraina differs from most other atolls in the world in that it has a large freshwater lake, an open lense, concealed within its luxuriant coconut palm forest; this is the only permanent freshwater lake in the whole of Kiribati.

Vostok Island is an uninhabited coral island in the central Pacific Ocean, part of the Line Islands belonging to Kiribati. Other names for the island include Anne Island, Bostock Island, Leavitts Island, Reaper Island, Wostock Island or Wostok Island. The island was first sighted in 1820 by the Russian explorer Fabian Gottlieb von Bellingshausen, who named the island for his ship Vostok.
