The Kikendatch Bay is a freshwater body that leads to the Gouin Reservoir, in the territory of La Tuque, in Haute-Mauricie, in the administrative region of Mauricie, in the province of Quebec, in Canada.

The route 400, connecting the Gouin Dam to the village of Parent, Quebec, serves the southern part of Kikendatch Bay, as well as the valleys of Jean-Pierre River and Leblanc River; this road also serves the peninsula which stretches north in the Gouin Reservoir on 30.1 kilometres (18.7 mi).

The surface of Kikendatch Bay is usually frozen from mid-November to the end of April, however, safe ice circulation is generally from early December to late March.

In 1832, the map of Arrowsmith (entitled British North America) identifies this post, as "mission center of Haut-Saint-Maurice" by the priest of Yamachiche, Quebec, Severin-Nicolas Dumoulin (1793–1853), first missionary, in 1837, to visit the population of Atikamekw since the voyage of the father Jacques Buteux in 1651.
