Malden Island is a low, arid atoll located in the central Pacific Ocean.

It is part of the Line Islands and belongs to the Republic of Kiribati. The island is situated south of the equator and south of Honolulu, Hawaii. It is located more than 1,000 miles west of the South American coast. The nearest land is the uninhabited Starbuck Island to the southwest. The closest inhabited place is Tongareva, also known as Penrhyn Island. Malden is a significant site for history, biology, and environmental protection. It currently serves as the Malden Island Wildlife Sanctuary.

The geography of the atoll is defined by a unique triangular shape.

The island is roughly an equilateral triangle with sides of about 5 kilometers. A large, shallow, and irregularly shaped lagoon fills the east central part of the island. This lagoon is entirely enclosed by land, except for narrow strips on the north and east sides. It connects to the open ocean only through underground channels. Because the lagoon is connected this way, the water is quite salty. Most of the island's land area is located to the south and west of this lagoon.

The topography of Malden Island is very low and flat. No part of the island rises more than 3 meters above sea level. The highest elevations are found along a rim that follows the coastline. The interior forms a depression that is only a few meters high in the west. In the east central part, the interior is actually below sea level where the lagoon sits. This shape means that the ocean cannot be seen from much of the interior. There is no standing fresh water on the island, though a fresh water lens might exist underground.

Malden Island has a complex history involving many different groups of people.

While no people lived there when Europeans arrived, there are 21 catalogued archaeological sites. These sites show that Polynesian people occupied the island in the past. The ruins include temple platforms called marae, house sites, and graves. These structures are similar to architectural forms found in Tonga and Raivavae. Later, European sailors began documenting the island in the early 1800s. Captain Samuel Bunker first sighted it in 1825.

The island was eventually named after Lieutenant Charles Robert Malden, a navigator on the HMS Blonde.

In the late 19th century, the island became a place of industry. Australian companies exploited large deposits of phosphatic guano from 1860 to 1927. Guano is bird waste used as a valuable agricultural fertilizer.

Life for the workers was very difficult due to the extreme aridity. There were no fresh water wells, so settlers used large distillation plants to create water. The workers used a unique railroad system to transport the guano. The cars were powered by large sails. Workers pushed empty carts up the tramway, and the southeastern winds blew the loaded cars back.

In the mid-20th century, the island was used for military purposes. The United Kingdom selected Malden as an instrumentation site for Operation Grapple.

In 1957, the British detonated three thermonuclear devices, or H-bombs, at high altitudes. These tests occurred a short distance offshore. The yields of these devices ranged between 200 and 720 kilotons. Today, the island is uninhabited and serves as a protected breeding ground. It is an important site for about a dozen species of seabirds. These include masked boobies, red-footed boobies, and various species of frigatebirds and terns.

The biological importance of Malden Island is tied to its isolation. It is a vital winter stop for migratory birds like the bristle-thighed curlew, which travels from Alaska. Nineteen species of migratory seabirds use the island. The vegetation is limited to sixteen species of vascular plants, with only nine being indigenous. Much of the land is covered in stunted Sida fallax scrub and grasses. Introduced species like feral cats and house mice are still present on the island. However, the island remains a critical sanctuary for marine life, including green turtles that nest on the beaches.
