Nassau County is a county located in the U.S. state of Florida. It is the northeasternmost county in the state. The county seat is Fernandina Beach. The population was 90,352 at the 2020 census. Nassau County is a constituent of the Jacksonville, Florida Metropolitan Statistical Area, which accommodates around 1.68 million inhabitants as of 2022. The county is situated in Northeast Florida with a land area of 726 square miles. The county's population has surged by more than 40,000 residents since the year 2000, driven by factors such as Nassau's nearness to downtown Jacksonville, the emergence of fresh residential projects, agricultural output, prominent tourist destinations, and a broadening tax foundation through the influx of novel industrial and business enterprises to the county. Nassau County is also a favored residential destination for military personnel stationed at bases in the adjacent Duval County, Florida and Camden County, Georgia. Nassau County celebrated 200 years with its bicentennial celebration in 2024.
