Scouting in Missouri has a long history, from the 1910s to the present day.

The Tribe of Mic-O-Say is an honor society used by two local councils of the Boy Scouts of America, the Pony Express Council at Camp Geiger Reservation, and the Heart of America Council at the H. Roe Bartle Scout Reservation. Similar programs exist or have existed in multiple other councils as well. The Tribe of Mic-O-Say is not a program of the National Council of the BSA. Mic-O-Say's ceremonies, customs, and traditions are loosely based on the folklore of various tribes of Native Americans. Both councils use both the Tribe of Mic-O-Say and the Order of the Arrow.
