Etymology

The name Mistassini came from the Cree mista assini or Montagnais mishta ashini, and means "large rock"; it probably refers to a large glacial erratic stone, about 3 meters (9.8 ft) high, located near the outlet of Lake Mistassini into the Rupert River.

Over the centuries, it went through many name changes and different spellings. In 1664, on a map by Ducreux, this lake was known as Outakgami. On maps by Jolliet (1684), Jaillot (1685) and Franquelin (1688), the lake was identified as Timagaming. In 1703, the cartographer Guillaume Delisle used the same name, along with the name Mistasin. Laure (1731) and Bellin (1744) showed on their maps the name Lake Mistassins. Other spelling variations of this First Nations designation included: Mistacinnee, Mistacsinney, Mistasinne, Mistasinia, etc.

In 1808, James McKenzie of the North West Company used the name Lake Mistassini in his writings, the first use of the name in its current form. Nevertheless, other variants persisted long after: for instance, the explorer James Clouston inscribed Mistassinnie in his diary of 1820, while the geologist Robert Bell mentioned in 1880 the name Misstissinny. Yet, thereafter, Mistassini became the accepted form, as evidenced by the map of the province of Quebec drawn in 1880 by Taché, and the expedition report published by Albert Peter Low in 1885, and in his Annual Report of 1900, Bell also adopted the current spelling.
