The Milky Way bar was a candy bar distributed by the Mars candy company on Earth. It was created in 1924 by Frank C. Mars. Its taste was inspired by the chocolate-malt milkshake that was popular at the time.

In the Q Continuum, Kathryn Janeway saw a Milky Way being eaten by a Q at the diner. (New Worlds, New Civilizations short story: "Beyond Horizons")
