The Alaska-Aleutians, commonly known as the Aleutian Islands, are a volcanic archipelago that extends westward from the Alaska Peninsula toward Russia. The chain consists of about 300 islands and covers roughly 1,200 miles (1,900 km) in length. The islands straddle the 180th meridian, creating a geographic link between the North Pacific and Bering Sea and forming a natural barrier between the Arctic and Pacific oceans.

The Aleutians lie on the Pacific Ring of Fire, with ongoing volcanic activity and earthquakes. The climate is maritime, characterized by mild temperatures relative to latitude, persistent cloud cover, strong winds, and high precipitation, especially on windward sides.

The islands are sparsely populated; major communities include Unalaska/Dutch Harbor on Unalaska Island and Adak on Adak Island. The economy centers on commercial fishing, seafood processing, and, to a lesser extent, tourism and government services.

The region has been inhabited for thousands of years by the Unangan (Aleut) people. Russian explorers arrived in the 18th century, followed by American control after 1867. The area played a strategic role in World War II during the Aleutian Campaign. The Aleut people maintain a distinct culture and language linked to the islands and surrounding coastlines.

The environment supports diverse wildlife, including seabirds, seals, and whales, with several protected areas such as the Alaska Maritime National Wildlife Refuge—the largest wildlife refuge in the United States. The region's ecosystems are sensitive to oil exploration and commerce, requiring careful stewardship.
