Passaic (/p??se?.?k/ p?-say-ik[21] or local /p??se?k/ p?-sayk[22]) is a city in Passaic County, New Jersey, United States. Located north of Newark on the Passaic River, it was first settled in 1678 by Dutch traders, as Acquackanonk Township. The city and river draw their name from the Lenape word "pahsayèk" which has been variously attributed to mean "valley" or "place where the land splits.

The city originated from a Dutch settlement on the Passaic River established in 1679 which was called Acquackanonk. Industrial growth began in the 19th century, as Passaic became a textile and metalworking center. Passaic was formed within Acquackanonk Township on March 10, 1869, and was incorporated as an independent village on March 21, 1871. Passaic
Passaic has been called "The Birthplace of Television". In 1931, experimental television station W2XCD began transmitting from DeForest Radio Corp. in Passaic. It has been called the first television station to transmit to the home, and was the first such station to broadcast a feature film. The Okonite company began manufacturing electrical cable here in 1888.
