In the United States, a principal city is the largest incorporated place with a population of at least 10,000 in a core-based statistical area (CBSA) or New England city and town area (NECTA), or if no incorporated place of least 10,000 population is present in the CBSA or NECTA, the largest incorporated place or census designated place (CDP) in the CBSA or NECTA. Additional places that meet specific criteria are also identified as principal cities.^[1] The title of each metropolitan or micropolitan statistical area consists of the names of up to three of its principal cities and the name of each state into which the metropolitan or micropolitan statistical area extends.^[2]

In the United States and Puerto Rico, the Office of Management and Budget identifies principal cities for each core-based statistical area (CBSA) and New England city and town area (NECTA).^[3] Principal cities are used primarily for naming CBSAs and NECTAs, as well as combined statistical areas and combined NECTAs.
