There are 67 counties in the state of Florida. It became a territory of the U.S. in 1821 with two counties complementing the provincial divisions retained as a Spanish territory: Escambia to the west and St. Johns to the east, divided by the Suwannee River. All of the other counties were apportioned from these two original counties. Florida became the 27th U.S. state in 1845, and its last county was created in 1925 with the formation of Gilchrist County from a segment of Alachua County. Florida's counties are subdivisions of the state government. In 1968, counties gained the power to develop their own charters. All but two of Florida's county seats are incorporated municipalities. The exceptions are Crawfordville, county seat of rural Wakulla County, and East Naples, located outside Naples city limits in Collier County.

The names of Florida's counties reflect its diverse cultural heritage. Some are named for Confederate political leaders and Spanish explorers, marking the influence of Spanish sovereignty, while others are named for Spanish saints, Native American placenames used by the Spanish, and political leaders of the United States. Natural features of the region, including rivers, lakes, and flora, are also commonly used for county names. Florida has counties named for participants on both sides of Second Seminole War: Miami-Dade County is partially named for Francis L. Dade, a Major in the U.S. Army at the time; Osceola County is named for a Native American resistance leader during the war.

Population figures are based on the 2010 United States Census. The population of Florida is 18,801,310, an increase of 17.6% from 2000. The average population of Florida's counties is 280,616; Miami-Dade County is the most populous (2,662,874) and Liberty County is the least (8,365). The average land area is 805 sq mi (2,085 km2). The largest county is Palm Beach County (2,034 sq mi, 5,268 km2) and the smallest is Union County (240 sq mi, 622 km2). The total area of the state is 65,795  sq miles; of this, the land area of the state constitutes 53,927 square miles (139,670 km2) while the water area constitutes 11,868  sq miles.

The Federal Information Processing Standard (FIPS) is used by the U.S. government to uniquely identify counties, and is provided for each entry. These codes link to the United States Census Bureau's "quick facts" for each county. Florida's FIPS code of 12 is used to distinguish from counties in other states. For example, Alachua County's unique nationwide identifier is 12001.
