The city was founded in 1724 as Saddle River Township, when New Barbados broke up into an array of smaller towns and villages. For nearly two hundred years the township remained mainly agricultural, thanks to the fertile land and a river nearby, with the exception of a series of mills built along the river. In the beginning of twentieth century many saw the town as the place to build rural homes, where those who worked in cities like Hackensack and New York often settled. In 1955 the town was renamed into Saddle Brook.
Today, Saddle Brook remains a typical suburban town, like tens of others in the county. The city often serves as an overnight residence to local visitors, travelers, and businessmen, which usually stay in one of the three big hotels of the city, totaling over 500 rooms. The city's convenient location at a junction of several major highways like Garden State Parkway and Route 4 provides easy access to major attractions and business centers, such as New York City.
