Overpeck Creek is a tributary of the Hackensack River, approximately 8 miles (13 km) long, in Bergen County in northeastern New Jersey in the United States.

The creek rises in Tenafly, on the west side of the Palisades, approximately one mile (1.6 km) from the Hudson River.

The creek lay along the main land route west of the Hudson and provided a consistently difficult barrier for transportation in the area until the construction of modern roads and bridges in the 19th century.

[8] Like the other tributaries of the Hackensack in the Meadowlands, the creek has suffered from severe pollution in the 20th century during the era of heavy industrialization.

During the 1950s, tide gates were installed on the creek that largely cut off the tidal flow into the surrounding wetlands.
