Lyndhurst was originally formed as Union Township on February 19, 1852 from portions of Harrison Township. On May 15, 1917, the area was incorporated by an Act of the New Jersey Legislature as the Township of Lyndhurst, based on the results of a referendum held one week earlier.
According to the United States Census Bureau, the township has a total area of 4.9 square miles (12.7 km²), of which, 4.7 square miles (12.0 km²) of it is land and 0.3 square miles (0.7 km²) of it (5.30%) is water.
As of the 2000 census, 33.8% of township residents were of Italian ancestry, the 19th-highest percentage of any municipality in the United States, and eighth-highest in New Jersey, among all places with more than 1,000 residents identifying their ancestry.
There were 7,877 households out of which 25.8% had children under the age of 18 living with them, 51.1% were married couples living together, 11.2% had a female householder with no husband present, and 33.9% were non-families. 28.8% of all households were made up of individuals and 12.6% had someone living alone who was 65 years of age or older. The average household size was 2.46 and the average family size was 3.06.
In the township the population was spread out with 19.1% under the age of 18, 7.6% from 18 to 24, 32.4% from 25 to 44, 23.1% from 45 to 64, and 17.7% who were 65 years of age or older. The median age was 40 years. For every 100 females there were 91.1 males. For every 100 females age 18 and over, there were 88.2 males. Lyndhurst has the highest proportion of single females ages 18-25.
The median income for a household in the township was $53,375, and the median income for a family was $63,758. Males had a median income of $42,359 versus $35,429 for females. The per capita income for the township was $25,940. About 2.8% of families and 4.6% of the population were below the poverty line, including 4.2% of those under age 18 and 7.6% of those age 65 or over.
On Election Day, November 7, 2006, one seat came up for election on the Township Committee to fill an unexpired term in office. Independent incumbent Joseph Abruscato (1,191 votes), who had been filling the seat, ran unopposed and was elected to serve the balance of the term. On October 24, 2007, the entire council switched party affiliation from Republican to Democrat.
Lyndhurst is in the Ninth Congressional District and is part of New Jersey's 36th Legislative District.

Lyndhurst, together with North Arlington and Rutherford was the site of the EnCap project, an effort to remediate landfills on the site and construct homes and golf courses on top of the cleaned up site. On May 27, 2008, the New Jersey Meadowlands Commission terminated its agreement with EnCap Golf Holdings, the company that had the contract to redevelop the site, after the company had missed targets to cleanup the landfills as part of the project.
A heroine emerged the day of the Kingsland Explosion. Tessie McNamara, who operated the company switchboard, was credited with 1,400 lives. As the fire raged on, Tessie stayed at the switchboard that Thursday afternoon. She plugged in each of the buildings and shouted the warning, "Get out or go up!" Thanks to her dedication, no one was killed in the fire.
