The area that is now Mahwah was originally formed as Hohokus Township on April 9, 1849, from portions of the former Franklin Township (now Wyckoff). While known as Hohokus Township, territory was taken to form Orvil Township (on January 1, 1886; remainder of township is now Waldwick), Allendale (November 10, 1894), Upper Saddle River (November 22, 1894), and Ramsey (March 10, 1908). On November 7, 1944, the area was incorporated by an act of the New Jersey Legislature as the Township of Mahwah, based on the results of a referendum held that day, replacing Hohokus Township.New Jersey Monthly magazine ranked Mahwah as its ninth best place to live in its 2008 rankings of the "Best Places To Live" in New Jersey.
The Lenape and ancestral indigenous peoples were the original inhabitants of Mahwah (the meeting place) and surrounding area. Their descendants have combined with other Native Americans and ethnicities and were recognized in 1980 by the state as the Ramapough Mountain Indians. They number approximately 5,000 people living around the Ramapo Mountains of northern New Jersey and southern New York. The tribe is officially recognized by New Jersey, but does not have federal recognition. Their tribal office is located on Stag Hill Road in Mahwah, and the Chief of the Ramapough Lenape Indian Nation is Dwaine Perry (as of March 2007).
Ford Motor Company operated the Mahwah Assembly plant from 1955, producing 6 million cars in the 25 years it operated before the last car rolled off the line on June 20, 1980. At the time of its completion, it was the largest motor vehicle assembly plant in the United States. The Ford plant, along with other businesses such as American Brake Shoe and Foundry Company, helped contribute to the economic development of the town and its reputation for low home property taxes. The Mahwah town sports teams remain named Thunderbirds in honor of the Ford plant.
Due to contractors' dumping of hazardous wastes at the Ringwood Mines landfill site before federal regulation, it has been designated as an EPA Superfund site which needs extensive environmental cleanup. In 2006, some 600 Ramapough Indians filed a mass tort claim against Ford for damages. Mahwah, and the closure of the Ford plant, is mentioned in the opening line of the 1982 Bruce Springsteen song "Johnny 99".

Mahwah is governed within the Faulkner Act (formally known as the Optional Municipal Charter Law) under the Mayor-Council system of municipal government (Plan B), implemented by direct petition as of July 1, 1984. The governing body consists of a mayor and a seven-member Township Council, with all members elected at-large to four-year terms of office in non-partisan elections held as part of the November general election in even years, with either three seats (and the mayoral seat) or four seats up for vote. The legislative power of the municipality is exercised by a seven-member Township Council. In September 2010, the township council voted to shift the township's non-partisan elections from May to November, citing increased voter participation and prospective savings of $30,000 associated with supporting each election, with the first November election taking place in 2012.
As of 2019[update], the Mayor of Mahwah is John Roth, who was elected to replace William Laforet and serve the balance of the term of office ending December 31, 2020. Mayor Roth was elected in November 2018 following a recall of the former mayor. Members of the Township Council are Council President David May (2020; elected to serve an unexpired term), Council Vice President George W. Ervin (2022), Janet Ariemma (2022), Robert M. Ferguson III (2022), Michelle Crowe Paz (2020; elected to serve an unexpired term), Jonathan Wong (2022) and James Wysocki (2020).
Then-Mayor Bill Laforet faced a recall election in November 2018, after a resident group submitted in June a list of 5,000 petition signatures that they had collected calling for the action, in excess of the 25% needed to place the measure in front of voters. In the November 2018 general election, Laforet was recalled from office and John Roth was elected mayor. The successful recall was the first in the county for at least 25 years.
Michelle Crowe Paz was appointed to fill the seat expiring in December 2020 that was vacated following the resignation of Steven Sbarra that became effective at the end of December 2017, and was elected in her own right in November 2018 to fill the unexpired term.
At the January 2017 reorganization meeting, David May was sworn in to fill the seat expiring in December 2020 that had been won by Jonathan Marcus in the November 2016 general election, but which Marcus decided not to accept; May was elected in his own right in the November 2017 general election, to serve the balance of the term.
In December 2016, the Township Council selected George Ervin to fill the seat that had been held by Mary Amoroso expiring in December 2018 that became vacant after she was elected the Bergen County Board of Chosen Freeholders; Ervin served on an interim basis until the November 2017 general election, when voters elected him in his own right to fill the balance of the term. Ervin was re-elected in the November 2018 election to fill a full four-year term, expiring in 2022.
In August 1997, due to personal debt, then-Mayor David J. Dwork shot and killed himself in the town's mayoral offices. There were also unverified allegations of corruption. Dwork was memorialized with a tree dedicated to him at the site of the Mahwah Public Library. Dwork was succeeded by Richard J. Martel, then a township council member, who served for 14 years until his own death, of natural causes, on March 7, 2011. Martel himself was succeeded by Council President John DaPuzzo as acting mayor.

The district's newest building, Lenape Meadows, was opened in 2002 and changed the way the district divided up grade levels. Since the K-3 grades are broken up by location in the township which determines the elementary school to attend, before Lenape Meadows was built, students of that section of town attended Commodore Perry School. Commodore Perry School, Betsy Ross, and George Washington originally only housed the K-2 grades and the entire 3rd grade class attended Joyce Kilmer. The construction of Lenape Meadows added enough room for 3rd grade students as well, allowing Betsy Ross and George Washington room to house their students for 3rd grade, too.
