Jericho is a community located within Stow Creek Township, in Cumberland County, in the U.S. state of New Jersey.

[1][2][3] Stow Creek, a tributary of the Delaware River, flows through the settlement, and a pond and dam are located there.

[4][5] Jericho was at one time an important mill town in the history of Cumberland and Salem counties.

[6] Originally called "Gravelly Run", the settlement began to flourish in 1680 when John Brick purchased 1,000 acres (400 ha) of land bordering Stow Creek, and erected sawmills and gristmills.

[6] The geologic area around Jericho contains Miocene epoch marl, and it is rich with fossils.
