Upper Saddle River is a borough in Bergen County, New Jersey, United States. As of the 2010 United States Census, the borough’s population was 8,208.

Upper Saddle River was settled in the 18th century principally by Dutch settlers who built mills along the Saddle River. The area was granted borough status in 1894 and remained principally rural until the 1950s. The suburban growth of New Jersey affected Upper Saddle River and surrounding municipalities, as the borough’s population increased tenfold from 1950 to 1970. The population has remained fairly constant since 1970.

Predominantly a residential community consisting of one-acre (4,000 m²) lots, Upper Saddle River also contains a library, police station, fire station, ambulance corps, municipal hall, and three primary schools. Commerce and industry are concentrated along the town’s western border along Route 17. Postal service is shared with the neighboring borough of Saddle River.

Upper Saddle River was formed as a borough by an act of the New Jersey Legislature on November 22, 1894, from portions of Hohokus Township and Orvil Township, based on the results of a referendum held two days earlier. The borough was formed during the “Boroughitis” phenomenon then sweeping through Bergen County, in which 26 boroughs were formed in the county in 1894 alone. Upper Saddle River’s referendum passed on November 20, one day after the referendum passed for Saddle River. The name of the river, and hence the borough, is thought to come from early explores who thought that the geography of the area resembled that of the Sadle Burn, the valley surrounding a stream in the Scottish area of Argyll.

As of the 2010 United States Census, there were 8,208 people, 2,639 households, and 2,299 families residing in the borough. The population density was 1,560.0 per square mile (602.3/km²).
