Joan Harrison was an English screenwriter and producer. She became the first female screenwriter to be nominated for the Best Original Screenplay Oscar when the category was introduced in 1940, and was the first screenwriter to receive two Academy Award nominations in the same year in separate categories, for co-writing the screenplay for the films Foreign Correspondent (1940) (original) and Rebecca (1940) (adapted), both directed by Alfred Hitchcock, with whom she had a long professional relationship.
