Marcella Daly (1901–1966) was an American film actress of the silent era. Daly was the daughter of Mr. and Mrs. P. H. Daly and a graduate of the Whittier School and Hollywood High School. In June 1924, Daly received publicity when casting director Lewis Mason committed suicide and left a note that said, in part, "Everything I have, please give to Marcella Daly."
