Marie Fedor was a stage actress from Boston, Massachusetts who performed in theater at the beginning of the 20th century.
She made her stage debut in Leah Kleschna, in December 1904, with the stock company of Minnie Maddern Fiske.
Reviewer Robert Butler commented on Fedor's acting: "She displayed unusual understanding of stage technique.
In the role of Frieda, an Austrian peasant girl, she appeared to an advantage that did not fail to win favorable comment.
Miss Fedor fitted decidedly well into the beautiful picture of the fifth act.
