The Northern New Jersey Square Dancers Association was founded in 1958 by 14 clubs in the northern New Jersey and nearby New York area. The NNJSDA currently serves 12 member clubs representing hundreds of dancers.

The Association holds about a dozen dance events each year, many featuring nationally popular callers. The annual Mini-Festival attracts dancers from throughout the region in halls offering Mainstream, Plus/Rounds, and Advanced/Challenge. The 50^th Annual Mini-Festival takes place on November 8, 2026 at the Glen Rock High School, Glen Rock, NJ. New dancers are celebrated at the annual class-level Midterm Dance.
