Badlesmere is a village and civil parish in the Swale district of Kent, England, about five miles south of Faversham. According to the 2001 census it had a population of 111. The church, dedicated to St Leonard, is described as 'interesting as a small, quite unremarkable church' which was not 'restored' in the Victorian era. Its interior is 13th century and 18th century. It has a complete set of Georgian box pews.

The adjoining mediaeval castle was demolished long ago. It was once home to the great family of Badlesmere whose head, Bartholomew de Badlesmere, was one of the most powerful men in England during the reign of King Edward II. The quiet village green (known as Badlesmere Lees) lies off the main road between Faversham & Ashford.

The parish has been linked for many years with that of Leaveland, whose mediaeval church, though very different from Badlesmere, has its own charm. Its crown-post roof and a handsome 16th century monument to a local family survived the Victorian restoration.
