Miami-Illinois (
Myaamia ) is a
Native American Algonquian language formerly spoken in the United States, primarily in
Illinois,
Missouri,
Indiana, western
Ohio and adjacent areas along the
Mississippi River by both the
Miami as well as the tribes of the
Illinois Confederacy, including the
Kaskaskia,
Peoria,
Tamaroa,
Cahokia, and
Mitchigamea. Since the 1990s the
Miami Tribe of Oklahoma has worked to revive it in a joint project with
Miami University in
Oxford, Ohio.
