Count: 0 — No incorporated cities, towns, boroughs, townships, or villages in New Jersey begin with the letter Y. This conclusion follows the official New Jersey municipal rolls and U.S. Census place files, which list every incorporated municipality by name and type. Note the absence is itself an interesting detail: Y is one of the few initial letters with no entries on the state’s A–Z municipal lists, reflecting naming patterns and the official definitions used by state and federal sources.
Expect this gap for logical and historical reasons. New Jersey place names come from English, Dutch, and Native American roots and from founders’ surnames, and very few of those sources begin with Y. Also expect technical exclusions: many named places that start with Y are unincorporated neighborhoods, park names, or census-designated places, and those are deliberately excluded when compiling a list of incorporated municipalities. Consult the New Jersey Department of State municipal directory and the U.S. Census Gazetteer files for the authoritative A–Z lists and for any nearby or related place names that nearly match the Y criterion.
