Ridgefield Park was formed as a village on June 15, 1892, within Ridgefield Township, based on the results of a referendum passed on June 6, 1892. Overpeck Township was formed on March 23, 1897, to be coextensive with Ridgefield Park village, and was created within Ridgefield Township for the purpose of administering a Board of Education. Portions of the village were taken gained in both 1921 and 1926 from Bogota and Teaneck. On May 31, 1938, Overpeck Township became Ridgefield Park Township. The village was named for the area's terrain.
The village's Fourth of July Parade, first established in 1894, is said to be the longest continuously celebrated such event in New Jersey and one of the oldest in the country. The village eliminated its July 4 fireworks in 2009, citing the $50,000 cost in the face of the difficult economy, but committed to retain its parade.(Wikipedia)
