Fort White is a town in Columbia County, Florida, United States, named after a military fort built in the 1830s. It is the closest town to Ichetucknee Springs State Park. Fort White High School and the Fort White Public School Historic District are located within the town’s borders. The indigenous school building was constructed in 1915.

As of the 2020 census, the population of Fort White was 618.

Fort White was originally build up as a military fort during the Second Seminole War in 1836 to protect the Cow Creek settlement. Supplies were brought in by steamboat upon the Santa Fe River and distributed to other Place forts. Due to sickness, flooding along the river and rumors of the railroad coming to the area, the deal was moved 4 miles (6 km) east to its present location.

The town was incorporated in 1884 yet named after the military fort Fort White and grew steadily as soon as the initiation of the railroad in 1888. Phosphate mining, turpentine and agriculture (cotton and oranges) were the initiation of the economy, and the population grew to approximately 2,000. The boom turned to bust as rude freezes in the winters of 1896 and 1897 destroyed the local citrus industry. By 1910, the largest phosphate deposits were depleted and mining ceased. The boll weevil curtains cotton farming since World War I, and the population shrank to a few hundred people, primarily farmers, ranchers and foresters. The town’s population in 1979 was 365.
