Northumberland County is a county located in the U.S. state of Pennsylvania. As of the 2020 census, the population was 91,647. Its county seat is Sunbury. The county was formed in 1772 from parts of Lancaster, Berks, Bedford, Cumberland, and Northampton Counties and named for the county of Northumberland in northern England. Northumberland County is a fifth class county according to the Pennsylvania's County Code.

Northumberland County comprises the Sunbury, PA Micropolitan Statistical Area, which is also included in the Bloomsburg-Berwick-Sunbury, PA Combined Statistical Area.

Among its famous residents, Joseph Priestley, the Enlightenment chemist and theologian, left England in 1796 due to religious persecution and settled on the Susquehanna River. His former house (originally purchased by chemists from Pennsylvania State University after a colloquium that founded the American Chemical Society) is a historical museum.


By 1813 the area once comprising the sprawling county of Northumberland had been divided over time and allotted to other counties such that lands once occupied by Old Northumberland at its greatest extent are now found in Centre, Columbia, Luzerne, Lycoming, Mifflin, Union, Clearfield, Clinton, Montour, Bradford, Lackawanna, Susquehanna, Wyoming, Tioga, Potter, McKean, Warren, Venango, Snyder, and Schuylkill Counties.

The Susquehanna River's tributaries in the county include the West Branch Susquehanna River, Chillisquaque Creek, Shamokin Creek, and the west flowing Mahanoy Creek, whose valley is a rail and road transportation corridor to ‹See Tfd›Tamaqua and points thereafter either east, north, or south such that: east along rail or US 209 through ‹See Tfd›Nesquehoning and historic ‹See Tfd›Jim Thorpe,; else northeast via ‹See Tfd›Beaver Meadows leading north into ‹See Tfd›Hazelton and the lower Wyoming Valley, or into the central Wyoming Valley skirting along the western Poconos via ‹See Tfd›White Haven and ‹See Tfd›Mountain Top; or otherwise head south through the Schuylkill Gap into ‹See Tfd›Port Carbon and thence west to the ‹See Tfd›Lancaster County or east via the greater ‹See Tfd›Reading area into the lower Schuylkill Valley and Philadelphia. The county has mountains in the south and north, with the rest being mostly rolling hills.

Natural Gas pipeline

In March 2016, Northumberland County announced a $700,000 deal with Williams Transco pipeline company. The County is granting a 9,700 foot right-of-way through its Anthracite Outdoor Adventure Area recreation park. Two parcels of county owned land are impacted: one in East Cameron Township and the other in Coal Township. The one time payment for the East Cameron Township parcel will be shared: County - 33.27%, township - 42.61% and Shamokin Area School District will receive 24.12%. For the Coal Township parcel: the County receives 33.13%, Coal Township gets 27.86% and the school district receives 39.01%. of the right-of-way payment. The County will also receive the value of the timber taken when the land is stripped. The recreation area is an environmentally restored former coal mining area. The pipeline will strip all vegetation and trees from the right-of-way in the outdoor recreation area. The Atlantic Sunrise Pipeline Project is a 178 mile long project, crossing 10 Pennsylvania counties and impacting 30 property owners in Northumberland County.
