Marie Tharp (1920-2006) was an American geologist and oceanographic cartographer who, in partnership with Bruce Heezen, created the first scientific map of the entire ocean floor.

Tharp's work revealed the presence of the Mid-Atlantic Ridge, causing a paradigm shift in earth science that led to acceptance of the theories of plate tectonics and continental drift.
