The Ramapough Mountain Indians (also spelled Ramapo), also known as the Ramapough Lenape Nation or Ramapough Lunaape Munsee Delaware Nation, are a group of approximately 5,000 people living around the Ramapo Mountains of Bergen and Passaic counties in northern New Jersey and Rockland County in southern New York, about 25 miles (40 km) from New York City. They were recognized in 1980 by the state of New Jersey as the Ramapough Lenape Nation but are not federally recognized. Their tribal office is located on Stag Hill Road on Houvenkopf Mountain in Mahwah, New Jersey. Since January 2007, the chief of the Ramapough Lenape Nation has been Dwaine Perry.
