24/7 Trauma & Biohazard Cleanup Near West Macclenny Macclenny, FL

Macclenny is a small city in northeast Florida and the county seat of Baker County, sitting just west of Jacksonville within the Jacksonville metropolitan area.

The town was settled in 1829, though it was not incorporated until 1939.

Macclenny was first known as Darbyville, after the Darby family, before being renamed for Carr Bowers McClenny, who married into the Darby family and bought up the surrounding land for timber, sawmills, and turpentine.

The spelling was changed from McClenny to Macclenny because the US Post Office would not allow a capital letter in the middle of a name; the town's first post office opened in 1890.

An 1888 yellow fever epidemic devastated the young town and killed most of its residents — the population stood at only 334 in the 1890 census.

Macclenny counted 7,304 residents at the 2020 census, up from 6,374 in 2010, and the Census Bureau estimated the population had grown to about 8,251 by July 2025.

Baker County, for which Macclenny serves as county seat, was created on February 8, 1861, and named for James McNair Baker.

The Battle of Olustee, the only major Civil War battle fought in Florida, was fought in Baker County in 1864.
