Portions of Alaska which are not contained in any of its 19 other organized boroughs

The Unorganized Borough is composed of the portions of the U. S. state of Alaska which are not contained in any of its 19 organized boroughs. While referred to as the "Unorganized Borough", it is not a borough itself, as it forgoes that level of government structure. It encompasses nearly half of Alaska's land area, 323,440 square miles (837,706 km2), and, as of the 2020 U. S. Census, it had a population of 77,157, which was 10.52% of the population of the state. The largest communities in the Unorganized Borough are the cities of Bethel, Unalaska, and Valdez.

This vast area has no local government other than that of school districts, municipalities, and tribal village governments. Except within some incorporated cities, all government services in the Unorganized Borough, including law enforcement, are provided by the state or by a tribal government. School districts in the Unorganized Borough are operated either by cities, in those limited instances when the city has chosen to undertake those powers, or through the general guidance of the Alaska Department of Education under the auspices of Rural Education Attendance Areas.

A number of boroughs have been incorporated since the Mandatory Borough Act, but most (the primary examples being North Slope, Northwest Arctic, and Denali) were incorporated to exploit a significant potential source of taxation, such as natural resource extraction and tourism. Many residents of the Unorganized Borough, particularly those in the larger communities which may be most susceptible to organized borough incorporation, have been opposed to such incorporation, and say the status quo suits them just fine. On the other hand, many Alaskans residing in organized boroughs feel that they unfairly subsidize residents of the Unorganized Borough, especially for education. In 2003, the Alaska Division of Community Advocacy identified eight areas within the Unorganized Borough meeting standards for incorporation. Bills have been introduced in the Alaska Legislature to compel these areas to incorporate, though as of 2009, none have been signed into law.
