'''Keflavík''' (pronounced ) is a town of around 10,000 inhabitants in the Reykjanes region in southwest Iceland.

It has now merged with Njarðvík and Hafnir to form a municipality called Reykjanesbær with a population of 14,000 (June 2008).

== History ==
thumb|300px|left| The harbour at Keflavík

Founded in the flight operations at the US during the 1940s. The airport used to hold a significant NATO military base and was a vital pre-jet refueling stop for trans-Atlantic commercial air traffic.

During WWII the military airfield served as a refueling and transit depot.  In the Norwegian and Greenland Seas, into the Atlantic Ocean.  During the Cold War, forces from the United States Air Force were added to provide radar monitoring, fighter intercept, in-flight refueling, and aerial/marine rescue.  After the collapse of the Soviet Union, however, the base's role was cast into doubt, as there was little threat from Russian long-range bombers or from hostile submarines carrying SLBMs passing through the North Sea into the Atlantic.  The base officially closed on September 30 2006, as the United States withdrew the remaining 30 military personnel.
The Airport remains, serving as Iceland's main international hub.

In Iceland, the town was renowned as a rich source of musicians during the 1960s and 70s, and is therefore also known as ''bítlabærinn'' or "The Beatle Town".

The local geography is dominated by fields of basalt rubble, interspersed with a few hardy plants and mosses.  On a clear day, one can see Snæfellsjökull across the bay, some 115 km away.
