The Miami Nation of Indiana (also known as the Miami Nation of Indians of the State of Indiana) is a group of individuals who identify as Miami and have organized as a 501(c)(3) nonprofit organization. The group's headquarters are at Peru, Indiana. The Indiana Miami, or Eastern Miami, signed a treaty with the United States on June 5, 1854; however, its federal recognition was terminated in 1897. The United States Congress has consistently refused to authorize federal recognition of the Indiana Miami as a tribal group separate from the Western Miami, the Miami Tribe of Oklahoma.
