Eudist Lake is in the unorganized territory of Lac-Jérôme in the Minganie Regional County Municipality of Quebec.

The French name is in honor of the Congregation of Jesus and Mary, or Eudists, an order that was founded in 1643 in Caen by Saint John Eudes (1601–1680).

The order was broken up during the French Revolution, then reformed in 1826 with the mission of education and propagation of the Christian faith.
