Hackensack is a city in Bergen County, New Jersey, that serves as the county seat and is the most populous municipality in the county.

The area was settled in 1665 as New Barbadoes and incorporated as New Barbadoes Township on October 31, 1693, and Hackensack was chosen as the Bergen County seat in 1710.

The name Hackensack derives from the language of its original Lenape inhabitants, who called the area "Ackingsah-sack."

After more than two centuries as New Barbadoes Township, the municipality was reincorporated as the City of Hackensack on November 21, 1921.

During the Revolutionary War, George Washington headquartered in Hackensack in November 1776 during the retreat across New Jersey, with his army camped on The Green across from the First Dutch Reformed Church on November 20, 1776.

A British raid on March 23, 1780, burned the Bergen County courthouse that then stood on The Green.
