Landenberg is an unincorporated community that is located in southern Chester County, Pennsylvania, United States.

It is, essentially, a post office address that covers parts of New Garden, London Britain and Franklin Townships.

The White Clay Creek (and preserve) bisects Landenberg, which also falls into two school districts: Avon Grove and Kennett Consolidated.

Landenberg's proximity to the White Clay Creek Preserve makes this area a favorite for local fisherman, hikers, bikers and outdoorsmen.

Landenberg is also home to many business people who commute to work in the nearby city of Wilmington, Delaware.
