This is a list of census-designated places in New Jersey. As of the 2010 United States Census, the U.S. state of New Jersey had 221 CDPs. Where the CDP is split between townships, the portion of the CDP's total population within each township is listed separately.

This article needs to be updated. The reason given is: large number of CDPs have been added for the 2020 census. (June 2021)

While the vast majority of CDPs are located entirely within a single municipality, there are eight CDPs that are split between different townships:

• Crandon Lakes - Hampton
  Stillwater
• Fort Dix - New Hanover (5,951), Pemberton (1,765) and Springfield (0)
• Kingston - South Brunswick (1,222) and Franklin (271).
• Lake Mohawk - Byram (1,824) and Sparta (8,092)
• McGuire AFB - New Hanover (737) and North Hanover (2,973)
• Ocean Acres - Barnegat (925) and Stafford (15,217)
• Richwood - Harrison (3,400) and Mantua (59)
• Upper Greenwood Lake - West Milford Township and Vernon Township

Three CDPs share the same name but are located in different counties:

• Silver Lake (Essex County), Silver Lake (Warren County) and Silver Lake (Cumberland County)

Three CDPs are split between two counties:

• Kingston - Middlesex County and Somerset County.
• Montclair State University - Passaic County and Essex County
• Upper Greenwood Lake - Passaic County and Sussex County

As part of the 2010 Census, the U.S. Census Bureau eliminated many CDPs that were coterminous with their parent townships. The following table lists CDPs that were split, otherwise substantially modified or eliminated.
