The City and Borough of Juneau, more commonly known simply as Juneau, is the capital city of the U.S. state of Alaska. Located in the Gastineau Channel and the Alaskan panhandle, it is a consolidated city-borough and the second-largest city in the United States by area. Juneau was named the capital of Alaska in 1906, when the government of what was then the District of Alaska was moved from Sitka as dictated by the U.S. Congress in 1900.
