Florence is a home rule-class city in Boone County, Kentucky, United States. Florence is one of the larger cities of Northern Kentucky, and part of the Greater Cincinnati Metropolitan Area. The population was 29,951 at the 2010 census.
The Florence area was originally known as Crossroads, because of the convergence of several roads from Burlington and Union at Ridge Road (now U.S. 25). By 1821, the area was known as Maddentown for Thomas Madden, a Covington attorney who owned a farm on the Burlington Pike. When Madden moved away, the area became known as Connersville in 1828 for Jacob Conner, a settler who assumed responsibility for the growing town. The town was finally renamed Florence because there was another Connersville in Harrison County. The name presumably is for Florence, Italy, but the specific etymology is unclear. It was incorporated on January 27, 1830, and grew quickly after the completion of the Covington-Lexington Turnpike in 1836.
