Port Monmouth is an unincorporated community and census-designated place (CDP) in Middletown Township, situated on the Raritan Bayshore of northern Monmouth County, New Jersey, United States.

[1] Tidal Compton Creek flows northward to Sandy Hook Bay through the east side of the community, while Pews Creek parallels it on the west side.

The 2010 United States census counted 3,818 people, 1,368 households, and 997 families in the CDP.

Of all households, 22.4% were made up of individuals and 9.9% had someone living alone who was 65 years of age or older.

The community was mentioned in a 1990 episode of Saturday Night Live during a Weekend Update sketch featuring Al Franken covering a cocaine deal in Port Monmouth.

[15] The tugboats Ocean Prince and Newport can be seen in the footage suggesting it was actually filmed locally in New York City for the show, as Port Monmouth and neighboring Belford Harbor are home to fishing vessels - which is noted by Franken during the sketch.

At the time of filming those tugboats were under the Amerada Hess Corporation, which had a storage facility and pier in Red Hook, Brooklyn.
