Carlstadt is a borough in Bergen County, in the U.S. state of New Jersey. As of the 2020 United States census, the borough's population was 6,372, an increase of 245 (+4.0%) from the 2010 census count of 6,127, which in turn reflected an increase of 210 (+3.5%) from the 5,917 counted in the 2000 census. Carlstadt was originally formed as a village by an act of the New Jersey Legislature on March 12, 1860, within Lodi Township. Most sources indicate that the community was named for Carl Klein, the leader of a group of early German settlers who led the project to establish the community though Henry Gannett stated that the name derived from the city of Karlovac in Croatia, which was known as "Carlstadt" in German. The Borough of Carlstadt was incorporated on June 27, 1894, formally set off from Bergen Township. 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.
