Mary Wallace Funk is an American aviator, commercial astronaut, and Goodwill Ambassador. She was the first female air safety investigator for the National Transportation Safety Board, the first female civilian flight instructor at Fort Sill, Oklahoma, and the first female Federal Aviation Agency inspector, as well as one of the Mercury 13.

A commercial astronaut is a person who has commanded, piloted, or served as an active crew member of a privately funded spacecraft. This is distinct from an otherwise non-government astronaut, for example Charlie Walker, who flies while representing a non-government corporation but with funding or training or both coming from government sources.
