The Ramapo Mountains are a forested chain of the Appalachian Mountains in northeastern New Jersey and southeastern New York, in the United States. They range in height from 900 to 1,200 feet (270 to 370 m) in New Jersey, and 900 to 1,400 feet (270 to 430 m) in New York.

Several parks and forest preserves encompass parts of the Ramapos (see Points of interest, below), and many hiking trails are in the Ramapos, including sections of the Appalachian Trail, which is maintained and updated in the Ramapo Mountains by the New York–New Jersey Trail Conference.

The mountains are named after the Ramapo Fault, which trends northeast to southwest, and separates the eastern Piedmont geologic province from the Highland province.

The Ramapos are composed of granite, gneiss, and marble, as old as 1.3 billion years.
