Mitchigamea or
Michigamea or
Michigamie were a tribe in the
Illinois Confederation. Not much is known about them and their origin is uncertain. Originally they were said to be from
Lake Michigan, perhaps the
Chicago area. Mitchie Precinct,
Monroe County in Southwestern Illinois takes its name from their transient presence nearby, north of the French
Fort de Chartres in the
American Bottom along the Mississippi. One of their villages in the American Bottom, inhabited from 1730 until 1752, is one of the region's premier
archaeological sites; it is known as the "
Kolmer Site".
