Ketchikan is a city in Ketchikan Gateway Borough, Alaska, United States, the southeasternmost city in Alaska. With a population at the 2010 census of 8,050, it is the sixth-most populous city in the state, and tenth-most populous community when census-designated places are included. The surrounding borough, encompassing suburbs both north and south of the city along the Tongass Highway (most of which are commonly regarded as a part of Ketchikan, albeit not a part of the city itself), plus small rural settlements accessible mostly by water, registered a population of 13,477 in that same census. Incorporated on August 25, 1900, Ketchikan is presently the earliest incorporated city in Alaska, owing to consolidation or unification elsewhere in Alaska resulting in dissolution of those communities' city governments. Ketchikan is located on Revillagigedo Island, so named in 1793 by Captain George Vancouver.
