The Lansdale Historical Society, founded in 1972, works to preserve and share collections that document the history of the Borough of Lansdale and the greater North Penn area of Montgomery County, Pennsylvania. The complex where the Historical Society is headquartered includes the Jenkins Homestead, a 1770-era Federalist-style farmstead that is the oldest building within the original borders of Lansdale.

Although some materials in Lansdale's collection (specifically deeds) predate the Borough's founding in 1872, the majority of its archival holdings, which span over 160 linear feet, date from the late 19th century to the present. These include photographs, negatives, slides, the records of businesses and fraternal organizations, tax assessments, family histories, obituaries, and various other materials relating to local history. The centerpiece of the collection is its newspaper holdings, including 133 years of the "Lansdale (North Penn) Reporter."
