Keflavík (pronounced ˈcʰɛplaˌviːk, meaning Driftwood Bay) is a town in the Reykjanes region in southwest Iceland. It is included in the municipality of Reykjanesbær whose population as of 2016 is 15,129.
In 1995, Keflavik merged with nearby Njarðvík and Hafnir to form the municipality of Reykjanesbær. Keflavík International Airport, the country's largest airport (serving nearby Reykjavík) is adjacent to the town.
Keflavík was founded by Scottish entrepreneurs and engineers in the 16th century, and developed on account of its fishing and fish processing industry.
In the 1940s an airport was built next to the town by the United States military, which served as an important refueling stop for trans-Atlantic flights, especially during World War II.
During the Cold War, Naval Air Station Keflavik played an important role in monitoring marine and submarine traffic from the Norwegian and Greenland seas into the Atlantic Ocean. Forces from the United States Air Force
