The borough is 15 miles (24 km) south of Allentown and Bethlehem and 47 miles (76 km) north of Philadelphia, making Quakertown a border town of both the Delaware Valley and Lehigh Valley metropolitan areas. It is considered part of the United States Census Bureau's Philadelphia−Camden−Wilmington (PA−NJ−DE-MD) MSA and the Delaware Valley. Quakertown is surrounded by Richland Township.
Quakertown was originally settled by members of the Religious Society of Friends, or Quakers. The settlement was not officially known as Quakertown until its first post office opened in 1803.
On September 18, 1777, during the American Revolutionary War, a convoy of wagons carrying the Liberty Bell from Philadelphia to Allentown, under the command of Col. Thomas Polk of Charlotte, North Carolina, stopped in Quakertown. The Liberty Bell was stored overnight behind the home of Evan Foulke (1237 West Broad Street), and the entourage stayed at the Red Lion Inn. The John Fries' Rebellion was also started in the Red Lion Inn in 1799.
