Microsoft Corporation is headquartered in Redmond, Washington.
Microsoft's main campus occupies a large area in the Overlake neighborhood of Redmond, east of Lake Washington. The company moved its headquarters from nearby Bellevue to Redmond in 1986, helping make the city strongly associated with the technology industry.
Microsoft was founded in 1975 by Bill Gates and Paul Allen. Although the company has major offices around the world, Redmond remains its corporate headquarters and a central base for engineering and business operations.
Seattle is often given as the answer because it is the best-known city in the region, but Microsoft's headquarters are across Lake Washington in Redmond. Bellevue is another nearby technology center, but it is not Microsoft's headquarters city.
