Count: 0 — There are no incorporated cities, towns, boroughs, townships, or villages in New Jersey whose official name begins with the letter X. Rely on authoritative sources such as the New Jersey Department of State municipal directory and the U.S. Census Bureau place files when checking incorporated names. Note that X is a rare initial letter in English and in the Dutch and Lenape naming traditions that shaped New Jersey place names, which helps explain this absence.
Understand the reasons: historical naming patterns and language make X an unlikely first letter for local place names, and official state and federal lists record only incorporated municipalities, excluding unincorporated neighborhoods, streets, businesses, and landmarks that might start with X. Recognize items that come close: several New Jersey place names contain the letter X (for example, Roxbury) but do not begin with it. Consult the state municipal directory or the U.S. Census place files for full A–Z coverage, and check unincorporated place and neighborhood lists if you want every local feature that might start with X.
