County constitutional officer (Florida)

In the U.S. state of Florida, county constitutional officers are independently elected officials in each county who lead departments and perform specific functions of the county's government. The Florida Constitution establishes five county constitutional officers: the sheriff, tax collector, property appraiser, supervisor of elections, and clerk of the circuit court. Elected state attorneys, public defenders, county commissioners, school board members, and the superintendents of schools may also be considered constitutional officers. In the event of the death, resignation, or removal from office of a county constitutional officer, the Governor of Florida is empowered to appoint a successor to fill the vacancy until the next regularly scheduled election.

Under Florida law, each county has state officers who are elected locally, and their salaries and office expenses are paid locally. Constitutional officers establish the budgets for their offices, independent of the operating budget set by the Board of County Commissioners. Although they operate independently, constitutional officers work in cooperation with the BCC in order to serve the public efficiently and cost-effectively. They are elected in partisan elections every four years, in concurrence with presidential elections and are not subject to term limits. The state constitution allows for counties to hold a referendum to abolish a constitutional officer in their county, with the exception of the position of clerk of court. Counties may also hold a referendum to establish their county's constitutional officers as non-partisan roles. While several counties have made small changes (for instance a non-partisan supervisor of elections in Leon or an independent comptroller in Orange), only one county, Miami-Dade, has made significant alterations, which were reverted in 2025.

The mayor of Jacksonville is a county constitutional officer, as per the Jacksonville Consolidation. Despite being independently elected county officials, the mayor of Miami-Dade County, mayor of Orange County, and Volusia County chair are not county constitutional officers.
