[2] Northampton Township was originally settled by English colonists who came with William Penn on his voyage to Pennsylvania.

It is drained by the Neshaminy Creek, which forms its entire northeastern boundary, into the Delaware River.

The township is made up of the following unincorporated communities and census-designated places: Other past and present place names include Bulltown, Chain Bridge, Cornell, Grenoble, Jacksonville, Rush Valley, Saint Leonard, Spring Garden, and White House.

On average, the wettest month of the year is July which corresponds with the annual peak in thunderstorm activity.

The plant hardiness zone is 7a with an average annual extreme minimum air temperature of 0.3 °F (−17.6 °C).

[14][17] The communities of Holland and Churchville had commuter train service until January 1983 via SEPTA's Fox Chase-Newtown Rapid Transit Line.

Service was "temporarily" suspended due to failing train equipment resulting in poor ridership.

In the ensuing years (particularly post-1995), there has been heavy interest in resuming passenger service by Bucks County officials.

Several housing booms throughout the 1980s and 1990s have resulted in homes being situated directly adjacent to the dormant rail line.

[18] Though rail service was initially replaced with a Fox Chase-Newtown shuttle bus, patronage remained light.

The largest is Tyler State Park, which sits on 1,711 acres of parkland and offers trails for biking, hiking and horse back riding as well as several athletic fields, playgrounds, a disc golf course and canoe rentals.

It operates out of a large visitor center offering two miles of hiking trails on its 55-acre nature preserve located adjacent to the Churchville Reservoir.
