The Flag of Mistissini is the official symbol representing the Cree community located in the Eeyou Istchee James Bay territory in Quebec, Canada. Adopted on May 27, 1983, the flag is a horizontal tricolor with three vertical bands, arranged from left to right, in the colors green, white, and blue. The design represents the Cree's connection with nature and their cultural heritage. The top band (green) signifies the forest, the middle band (white) symbolizes the snowy tundra, and the bottom band (blue) represents the rivers and lakes. A stylized representation of a caribou, significant to the Cree people, is depicted in the center, symbolizing their spiritual connection with this animal. The Flag of Mistissini serves as an emblem of cultural identity and community pride for the residents of the Mistissini Cree Nation.
