Anchorage (officially called the Municipality of Anchorage; Dena'ina: Dgheyay Kaq'; Dgheyaytnu) is a unified municipal consolidated city-borough in the U.S. state of Alaska, on the West Coast of the United States. With an estimated 288,000 residents in 2019, it is Alaska's most populous city and contains nearly 40% of the state's population. The Anchorage metropolitan area, which includes Anchorage and the neighboring Matanuska-Susitna Borough, had a population of 396,317 in 2019, accounting for more than half the state's population. At 1,706 square miles (4,420 km2) of land area, the city is the fourth-largest by area in the United States and larger than the smallest state, Rhode Island, which has 1,212 square miles (3,140 km2).
Anchorage is in Southcentral Alaska, at the terminus of the Cook Inlet, on a peninsula formed by the Knik Arm to the north and the Turnagain Arm to the south. The city limits span 1,961.1 square miles (5,079.2 km2), encompassing the urban core, a joint military base, several outlying communities and almost all of Chugach State Park.
Due to its location, almost equidistant from New York City and Tokyo, Anchorage lies within 9+1⁄2 hours by air of nearly 90% of the industrialized world. For this reason, Ted Stevens Anchorage International Airport is a common refueling stop for international cargo flights and home to a major FedEx hub, which the company calls a "critical part" of its global network of services.
Anchorage has won the All-America City Award four times: in 1956, 1965, 1984–85, and 2002, from the National Civic League. Kiplinger has named it the United States' most tax-friendly city.
Russian presence in south-central Alaska was well-established in the 19th century. In 1867, U.S. Secretary of State William H. Seward brokered a deal to purchase Alaska from Imperial Russia for $7.2 million, or about two cents an acre ($111.3 million in 2019 dollars). His political rivals lampooned the deal as "Seward's folly," "Seward's icebox," and "Walrussia." In 1888, gold was discovered along Turnagain Arm just south of modern-day Anchorage.
Alaska became an organized incorporated United States territory in 1912.
