Nora O'Mahoney (1912–1989) was an Irish actress and lay missionary, known for Molly Malloy in Darby O'Gill and the Little People (1959) and as Godmother in Wanderly Wagon (1967–1982).

Born in Dublin in 1912, O'Mahoney started in theatre, and worked extensively in the 1930s and 1940s, including plays such as Drama at Inish (1933), Le Bourgeois Gentilhomme (1941), and The United Brothers (1942).

In 1959 she played a character named Molly Malloy in two productions, Darby O'Gill and the Little People (1959) and in Walt Disney's Wonderful World of Color (1959).

Soon after these two roles she gave up acting for a time, working as a lay missionary in Rhodesia, where she was Bishop Lamont's secretary for several years until she became ill, and was invalided home to Ireland.
