Midway Islands is an unincorporated territory of the United States located in the North Pacific Ocean. It is a group of three islands - Sand Island, Eastern Island, and Spit Island - with a total land area of only 2.4 square miles (6.2 square kilometers).

The islands were originally inhabited by Polynesians, and later discovered by European explorers. In the 19th century, the islands became an important refueling stop for ships traveling across the Pacific.

During World War II, Midway Islands played a crucial role in the Pacific Theater. In 1942, the Battle of Midway was fought nearby, resulting in a decisive victory for the United States over Japan. The islands served as a military base until 1993, when they were turned over to the United States Fish and Wildlife Service for conservation purposes.

Today, Midway Islands are a National Wildlife Refuge, home to over 1 million seabirds, including albatrosses and petrels. The islands are also a popular spot for ecotourism, with visitors able to observe the wildlife and learn about the islands' history. However, access to the islands is strictly regulated and limited to guided tours.
