Port Norris is an unincorporated community and census-designated place (CDP)[9] located within Commercial Township, in Cumberland County, in the U.S. state of New Jersey.

[12] Legislation was passed in 1911 allowing voters to choose to incorporate Port Norris as a borough, independent from Commercial Township, but it was defeated in a referendum.

[13] On a late night in September 2007, an undercover operation to put a halt to the drag racing was commenced, and up to 62 people were caught participating in a major drag race gathering.

The 2010 United States census counted 1,377 people, 481 households, and 355 families in the CDP.

[12] As of the 2000 United States Census[6] there were 1,507 people, 514 households, and 380 families residing in the CDP.

In the Port Norris area are the communities of Bivalve and Shell Pile.

This is a community of about 1,000 Negroes living in wooden barracks erected on stilts over the salt marshes.

Bivalve and Shell Pile are now mostly ghost towns, with a combined population of less than 50.

In Cruising the Chesapeake; a Gunkholer's Guide, William Shellenberger says:[17] As the name indicates this is an oystering port, probably the busiest on the Delaware.
