Gitchi Manitou
Gitchi Manitou (or Gichi-Manidoo), in traditional Algonquian First Nations culture, is the Great Spirit, the Creator of all things and the Giver of Life.
Gitchi Manitou is those cultures' analogue to the Christian God. When early Christian missionaries preached the Gospel to the Algonquian peoples, they absorbed Gitchi Manitou as a name for God through the process of syncretism. This can be seen, for example, in the words of the "Huron Carol".
