Dame Frances Margaret Anderson, AC, DBE (February 10, 1897 – January 3, 1992), known professionally as Judith Anderson, was an Australian actress who had a successful career in stage, film and television. Considered one of the greatest classical stage actors of the 20th century, she has two Emmy Awards and a Tony Award to her name, as well as a nomination for a Grammy Award and an Academy Award each.

She began her acting career in Australia but her ambition brought her to New York in 1918. She established herself as one of the greatest theatrical actresses and was a major star on Broadway throughout the 1930s, 1940s and 1950s. Her notable stage works included the role of Lady Macbeth, which she played first in the 1920s, and gave an Emmy Award-winning television performance in Macbeth (1960). Anderson's long association with Euripides's "Medea" began with her acclaimed Tony Award-winning 1948 stage performance in the title role. She appeared in the television version of Medea (1983) in the supporting character of the Nurse.
