[18] The name Pohatcong is thought to be derived from the Lenni Lenape Native American term meaning "stream between split hills".

On March 24, 1881, Chapter 145 of the Acts of the New Jersey General Assembly was published defining and creating Pohatcong Township.

The act to form Pohatcong had been introduced by Assemblyman William Fritts and, once law, was to take effect January 1 of the following year.

Pohatcong township's name comes from Lenape Native Americans, who called the area "split hills stream outlet".

[32] The township's economic data (as is all of Warren County) is calculated by the US Census Bureau as part of the Lehigh Valley / Allentown-Bethlehem-Easton, PA-NJ Metropolitan Statistical Area.

[41] As of the 2000 United States census,[13] there were 3,416 people, 1,341 households, and 989 families residing in the township.

43 acres (17 ha) of the mall is located in Pohatcong, with the portion of the property in the township being assessed for $39.8 million, one of the highest valuations in the municipality.

[43] The government is comprised of the Mayor and the four-member Township Council, with all positions elected at-large on a non-partisan basis.

The shift, which took effect in November 2012, was intended to save the municipality $8,000 a year in costs associated with conducting the election.

[45] As of 2022[update], the Mayor of Pohatcong Township is David S. Slack, whose term of office expires on December 31, 2023.

[46] Members of the Township Council are Stephen Babinsky (2024), Ingrid Gray (2023), Kevin J. Melvin (2022) and John S. Stillo (2022).

[2][47][48][49][50] In September 2019, Ingrid Gray was appointed to fill the seat expiring in December 2020 that had been held by Anthony S. Vangeli until he left office.

[51] At 22 years of age when he was inaugurated on July 1, 2011, James R. Kern III became the youngest municipal executive serving in office in the State of New Jersey.

[55] For the 119th United States Congress, New Jersey's 7th congressional district is represented by Thomas Kean Jr. (R, Westfield).

[57] For the 2024-2025 session, the 23rd legislative district of the New Jersey Legislature is represented in the State Senate by Doug Steinhardt (R, Lopatcong Township) and in the General Assembly by John DiMaio (R, Hackettstown) and Erik Peterson (R, Franklin Township).

[62][63] Constitutional officers of Warren County are: Clerk Holly Mackey (R, Alpha; 2027),[64][65] Sheriff James McDonald Sr. (R, Phillipsburg; 2025)[66][67] and Surrogate Michael J. Doherty (R, Washington; 2025).

[71] Among the township's 2010 Census population, 64.7% (vs. 62.3% in Warren County) were registered to vote, including 83.7% of those ages 18 and over (vs. 81.5% countywide).

[92] Trans-Bridge Lines operates the New Jersey Transit 890 and 891 bus routes, which connect Pohatcong Township with Easton, Pennsylvania.
