Consolidated city-county in the context of "List of cities in Kentucky"

In the United States, a county or county equivalent is an administrative subdivision of a state or territory, typically with defined geographic boundaries and some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively. Counties and other local governments exist as a matter of U.S. state law, so the specific governmental powers of counties may vary widely between the states, with many providing some level of services to civil townships, municipalities, and unincorporated areas. Certain municipalities are in multiple counties. Some municipalities have been consolidated with their county government to form consolidated city-counties or have been legally separated from counties altogether to form independent cities. Conversely, counties in Connecticut and Rhode Island, eight of Massachusetts's 14 counties, and Alaska's Unorganized Borough have no government power, existing only as geographic distinctions.

The United States Census Bureau uses the term "county equivalent" to describe places that are comparable to counties, but called by different names. Louisiana parishes, the organized boroughs of Alaska, independent cities, and the District of Columbia are equivalent to counties for administrative purposes. Alaska's Unorganized Borough is further divided into 11 census areas that are statistically equivalent to counties. In 2024, the U.S. Census Bureau began to also recognize Connecticut's councils of governments, which took over some of the regional powers from the state's former county governments, as county equivalents.

This is a list of the most populous municipal corporations of the United States. As defined by the United States Census Bureau, an incorporated place includes cities, towns, villages, boroughs, and municipalities. A few exceptional census-designated places (CDPs) are also included in the Census Bureau's listing of incorporated places. Consolidated city-counties represent a distinct type of government that includes the entire population of a county, or county equivalent. Some consolidated city-counties, however, include multiple incorporated places. This list presents only the portion of such consolidated city-counties that are not a part of another incorporated place.

In the United States, an independent city is a city that is not in the territory of any county or counties and is considered a primary administrative division of its state. Independent cities are classified by the United States Census Bureau as "county equivalents" and may also have similar governmental powers to a consolidated city-county or a unitary authority. However, in the case of a consolidated city-county, a city and a county were merged into a unified jurisdiction in which the county at least nominally exists to this day, whereas an independent city was legally separated from any county or merged with a county that simultaneously ceased to exist even in name.

Of the 41 independent U.S. cities, 38 are in Virginia, whose state constitution makes them a special case. The three independent cities outside Virginia are Baltimore, Maryland; St. Louis, Missouri; and Carson City, Nevada. Baltimore is the most populous independent city in the United States.

Most U.S. states and territories have at least two tiers of local government: counties and municipalities. Louisiana uses the term parish and Alaska uses the term borough for what the U.S. Census Bureau terms county equivalents in those states. Civil townships or towns are used as subdivisions of a county in 20 states, mostly in the Northeast and Midwest.

Population centers may be organized into incorporated municipalities of several types, including the city, town, borough, and village. The types and nature of these municipal entities are defined by state law, and vary from state to state. In addition to these general-purpose local governments, states may also create special-purpose local governments. Depending on the state, local governments may operate under their own charters or under general law, or a state may have a mix of chartered and general-law local governments. Generally, in a state having both chartered and general-law local governments, the chartered local governments have more local autonomy and home rule. Municipalities are typically subordinate to a county government, with some exceptions. Certain cities, for example, have consolidated with their county government as consolidated city-counties. In Virginia, cities are completely independent from the county in which they would otherwise be a part. In some states, particularly in New England, towns form the primary unit of local government below the state level, in some cases eliminating the need for county government entirely. Many rural areas and even some suburban areas of many states have no municipal government below the county level.

This list ranks the top 150 U.S. cities (incorporated places) by 2025 land area. Total areas including water are also given, but when ranked by total area, a number of coastal cities appear disproportionately larger. San Francisco is an extreme example: water makes up nearly 80% of its total area of 232 square miles (601 km).

In many cases an incorporated place is geographically large because its municipal government has merged with the government of the surrounding county. In some cases the county no longer exists, while in others the arrangement has formed a consolidated city-county (or city-borough in Alaska, or city-parish in Louisiana); these are shown in bold. Some consolidated city-counties, however, include multiple incorporated places. In such cases, this list presents only that portion (or “balance”) of such consolidated city-counties that are not a part of another incorporated place; these are indicated with asterisks (*). Cities that are not consolidated with or part of any county are independent cities, indicated with two asterisks (**).

Juneau (/ˈdʒuːnoʊ/ JOO-noh; Tlingit: Dzántik'i Héeni [ˈtsʌ́ntʰɪ̀kʼɪ̀ ˈhíːnɪ̀] transl. Base of the Flounder's River), officially the City and Borough of Juneau, is the capital of the U.S. state of Alaska, located along the Gastineau Channel and the Alaskan panhandle. 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. On July 1, 1970, the City of Juneau merged with the City of Douglas and the surrounding Greater Juneau Borough to form the current consolidated city-borough, which ranks as the second-largest municipality in the United States by area and is larger than both Rhode Island and Delaware.

Downtown Juneau is nestled at the base of Mount Juneau and it is across the channel from Douglas Island. As of the 2020 census, the City and Borough had a population of 32,255, making it the third-most populous city in Alaska after Anchorage and Fairbanks, but the sixth-least populous U.S. state capital. Juneau experiences a daily influx of 21,000 people or more from visiting cruise ships between the months of May and September.

The U.S. state of Louisiana is divided into 64 parishes (French: paroisses), making it the only state besides Alaska to call its primary subdivisions something other than "counties". Louisiana's usage of the term "parish" for a geographic region or local government dates back to the French colonial era and is connected to ecclesiastical parishes.

Thirty-eight parishes are governed by a council called a police jury. The remaining 26 have various other forms of government, including: council-president, council-manager, parish commission, and consolidated parish/city.
