Mount Hope is an unincorporated community and census-designated place[5] (CDP) that is a part of Rockaway Township in Morris County, New Jersey, United States.

John Jacob Faesch was the first to develop Mount Hope into an iron plantation with the erection of a stone furnace in 1772 and operated the facility until his death in 1799.

Various owners and lessees ran the furnace until 1831 when the Mount Hope Mining Company was incorporated in response to the opening of the Morris Canal and its transportation opportunities.

Operations ceased from 1893 to 1899 due to financial panics, the opening of the Mesabi Range in Minnesota and cheaper imported iron ore from South America.

The Mount Hope Miners' Church was added to the National Register of Historic Places in 2012 for its significance in architecture, social history, and religion.
