Indian Mills is an unincorporated community located within Shamong Township in Burlington County, New Jersey, United States. It was the site of Brotherton Indian Reservation, the only Indian reservation in New Jersey and the first in America, founded for the Lenni Lenape tribe. Brotherton also went by the name "Edgepillock" or "Edgepelick". The Brothertown Indians left New Jersey to join the Stockbridge Indians in western New York state, and eventually agreed to move to eastern Wisconsin.
