Matagami is a small town in Quebec, Canada. It is located north of Amos, on Matagami Lake, at the northern terminus of Route 109 and the start of the James Bay Road (French: Route de La Baie James). Matagami was founded in 1963 with the development of mining in the area. Previously, it existed only as a very small prospecting camp accessible only by float plane, but after a viable mineral deposit was found in the late 1950s a permanent settlement began to be established.
In 1962, the Quebec Toponomy Commission attempted to name the new community Mazenod after Charles-Joseph-Eugène de Mazenod, the founder of the Missionary Oblates of Mary Immaculate, but after a public outcry by local residents the community was named after Matagami Lake. The first church service in Matagami was held on 17 April 1962.
