Pines Lake is a unincorporated community on a lake in Wayne, in Passaic County, New Jersey, United States. Pines Lake was started as a vacation community around a man-made lake approximately 1.5 miles long and a half mile wide in the 1920s. Many of the original homes were modified log cabins. A large number of these log cabins, built of American chestnut in the 1930s, are still occupied as year-round homes. Gradually the neighborhood became approximately 500 high end to moderate suburban homes.
