Miami Tribe of Oklahoma

The Miami Tribe of Oklahoma (Miami-Illinois: myaamionki noošonke siipionki) is the only federally recognized Native American tribe of Miami Indians in the United States. The people are descended from Miami who were removed in the 19th century from their traditional territory in present-day Indiana, Michigan, and Ohio.

The name (Miami-Illinois: myaamionki noošonke siipionki, translates as "Miami homelands along the Neosho River". The name 'Miami' derives from Myaamia (plural Myaamiaki), the tribe's autonym (name for themselves) in their Algonquian language; it appears to have been derived from an older term meaning 'downstream people’. Some scholars contended the Miami called themselves the Twightwee (also spelled Twatwa), supposedly an onomatopoeic reference to their sacred bird, the sandhill crane. However, recent studies have shown that Twightwee derives from the Delaware language exonym name for the Miamis, tuwéhtuwe, a name of unknown etymology. Some Miami have stated that this was only a name used by other tribes for the Miami, and not their autonym. They also use Mihtohseeniaki, "the people." The Miami continue to employ this autonym today.

Tribal citizens traditionally spoke the Miami-Illinois language, one of the Algonquian languages, but few do today. The tribe partners with Miami University, and one result of that partnership is the Myaamia Center. The Myaamia Center is working to revitalize the language and culture. The Myaamia language is particularly well-documented in early sources (including a complete Illinois-French dictionary). The tribe and the university work together to conduct research projects to revitalize Miami language and culture, and to offer university students opportunities to visit and work with the tribe on various projects.

The tribe is headquartered in Miami, Oklahoma. Of the over 7,000 enrolled tribal citizens, 775 live in the state of Oklahoma. The Miami Tribe issues its own tribal vehicle tags and operates its own housing authority.

As of 2025^[update], the current administration is:

Aatotankiki Myaamiaki is the Miami Nation quarterly newspaper. The tribe is in the process of building the Myaamia Complex, for the benefit of tribal elders, to house the food program and tribal library.

To provide economic development for the community, the tribe created Miami Nation Enterprises, which oversees tribally owned companies. These include Miami Business Services, which provides personnel, information technologies, and business supplies; Miami Designs, which provides graphic art and promotional materials; Miami Cineplex, a movie theater and arcade; and TSI Global Companies, a systems integrator with expertise in audiovisual systems, low voltage cabling, security and access control, as well as electrical contracting. Additionally, the tribe owns one smokeshop and two casinos (Prairie Sun and Prairie Moon). Their estimated annual tribal economic impact is $16,700,000.

The tribe holds an annual powwow late in June and a stomp dance every winter in late January. The Myaamia Center continues research directed by the Miami Tribe of Oklahoma to revitalize language and culture.
