How Many Counties Make Up the State of Florida?

The First and Last Counties

The 67 counties of today grew from a much simpler map. When the United States acquired Florida from Spain in 1821, the new territory was split into just two original counties:

1. Escambia County (to the west)
2. St. Johns County (to the east)

The dividing line between them was the Suwannee River. As the population grew, these two massive counties were repeatedly split to create new counties. This process continued for over a century.

The last county to be formed was Gilchrist County, which was established in 1925.

Florida Counties by the Numbers

Florida's counties vary dramatically in size and population.

• Most Populous: Miami-Dade County is the most populous county, serving as a bustling hub of international culture and commerce.
• Least Populous: Liberty County, located in the panhandle, holds the title of the least populous, offering a quiet, rural contrast.
• Largest by Area: Palm Beach County is the largest county by total area, though Collier County (home to Naples) has the largest land area, much of which is covered by the Everglades.
• Smallest by Area: Union County, in North Florida, is the smallest county by land area.

The state of Florida is divided into 67 counties, which serve as the primary administrative divisions. When the U.S. acquired Florida in 1821, the territory was split into just two original counties: Escambia and St. Johns, divided by the Suwannee River. The current 67-county map was finalized in 1925 with the creation of Gilchrist County.

Florida's counties vary significantly in size and population. Miami-Dade County is the most populous, while Liberty County in the panhandle has the fewest residents. In terms of physical size, Palm Beach County is the largest by total area, while Union County is the smallest.
