The Borough of Mount Penn is a small community in southeastern Pennsylvania with the City of Reading to its west, the Township of Exeter to the east, and the Township of Lower Alsace along both the north and south borders. The Borough comprises 262 acres (.4 square miles) and has a population of 3,016. It has been a residential community since its founding in 1903.

The area from which Mount Penn emerged began as a land grant from the King of England to William Penn. The formation of Mount Penn Borough began in 1902 when a group of residents and landowners petitioned the court to create the Borough. On January 7, 1903, the Borough of Mount Penn became official.

There is a small triangle of land at the intersection of 23rd Street and Perkiomen Avenue that is home to the Memorial Clock, erected in honor of the veterans who served during war time. The Memorial Clock was dedicated on July 18, 1949.

Known as "The Friendly Borough," Mount Penn will celebrate its 100th anniversary next year. A committee is planning events to celebrate this noteworthy occasion; watch this page for upcoming events.
