Marc-Joseph Marion du Fresne (22 May 1724 – 12 June 1772) was a French privateer, East India captain, and explorer. The expedition he led to find the hypothetical Terra Australis in 1771 made important geographic discoveries in the south Indian Ocean and anthropological discoveries in Tasmania and New Zealand. In New Zealand, they spent longer living on shore than any previous European expedition. Half way through the expedition's stay, Marion was killed during a military assault by Ngare Raumati: one of the oldest Māori tribes from the Whangārei region.

He is commemorated with the toponyms Marion Island, South Africa and Marion Bay, Tasmania, as well in the name of two successive French oceanic research and supply vessel the Marion Dufresne (1972) and the Marion Dufresne II, which service the French Southern Territories of Amsterdam Island, the Crozet Islands, the Kerguelen Islands, and Saint Paul Island.
