Woodcliff Lake is a borough in Bergen County, New Jersey, United States. As of the 2010 Census, the borough’s population was 5,730, reflecting a decline of 15 (-0.3%) from the 5,745 counted in the 2000 Census, which had in turn increased by 442 (+8.3%) from the 5,303 counted in the 1990 Census. Most of the borough mandates a minimum lot size of 22,500 square feet (2,090 m²) for single-family homes, with portions on the borough’s east zoned for 15,000 square feet (1,400 m²) and portions of the borough’s northwest and southwest zoned for 30,000 square feet (2,800 m²) lots.

Woodcliff Lake is also the name of the reservoir that lies primarily within the borough, with a small portion at the southeastern edge located in neighboring Hillsdale.

The borough was originally incorporated as the Borough of Woodcliff, on August 31, 1894, from parts of Orvil Township and Washington Township, based on the results of a referendum held three 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. The borough derives its name from the characteristics of its geography.

On March 1, 1910, after the creation of the reservoir, the name of the borough was changed to Woodcliff Lake, to match the name of the post office. Prior to the creation of ZIP codes as a way to uniquely identify addresses, United States Postal Service policy was that two post offices in a state could not have the same name, and there was already a “Woodcliff” in Hudson County. On January 1, 1956, and again on July 1, 1958, Woodcliff Lake exchanged sections of land with Park Ridge. On October 13, 1960, portions were exchanged with Hillsdale.

As of the 2010 United States Census, there were 5,730 people, 1,916 households, and 1,600 families residing in the borough. The population density was 1,682.7 per square mile (649.7/km²). There were 1,980 housing units at an average density of 581.5 per square mile (224.5/km²).
