The Hiawatha Belt is a national belt of the Haudenosaunee.
In the center of flag is a symbol of a great white pine, which also represents the Onanogaga Nation. The squares flanking both sides represent the remaining nations that make of the Iroquois Confederacy: Seneca, Cayuga to the left of the pine tree and the Oneida and Mohawk Nations to the right of the pine trees.
