American engineer Mary G. Ross (born 1908) made notable contributions in aerospace technology, particularly in areas related to space flight and ballistic missiles.

Mary G. Ross was part of the original engineering team at Lockheed's Missile Systems Division, where she worked on a number of defense systems, and contributed to space exploration efforts with her work relating to the Apollo program, the Polaris reentry vehicle, and interplanetary space probes.
