Little Falls is a township in Passaic County, New Jersey, United States. The township was named for a waterfall on the Passaic River at a dam near Beattie Mill.

As of the 2010 census, the township’s population was 14,432, reflecting an increase of 3,577 (+33.0%) from the 10,855 counted in the 2000 Census, which had in turn declined by 439 (-3.9%) from the 11,294 counted in the 1990 Census.

Little Falls traces its first settlement to 1711 when seven Bergen Dutch settlers banded together to begin farming. The Speer Homestead dates from circa 1785 (and may have originally been built in 1680).

The Morris Canal, once an important artery of trade and transportation until 1925 between the Delaware and Hudson rivers, wound its way through the township and vestiges of it still remain, some parts of which are a greenway.

Little Falls was incorporated as a township by an act of the New Jersey Legislature on April 2, 1868, from portions of Acquackanonk Township. On March 25, 1914, portions of the township were taken to form the borough of West Paterson (now Woodland Park).
