Ludlow is a home rule-class city in Kenton County, Kentucky, United States. The population was 4,407 at the 2010 U.S. census. Located on the Ohio River, Ludlow is a suburb of Covington, Kentucky, and Cincinnati, Ohio. It received its greatest period of early growth as a rail station.
In 1790, the land that is now Ludlow was given to Gen. Thomas Sandford as a grant in recognition of his service during the Revolutionary War. Sandford traded the land to Thomas D. Carneal for land in what is now Ft. Mitchell. Carneal had Elmwood Hall built on the riverfront in 1818. It still stands (as of 2011) at 244 Forest Avenue and is a private residence.
