Manfred Noa (1893–1930) was a German film director. Noa was described by Vilma Bánky, who he directed twice, as her "favourite director". Noa's 1924 film Helena has been called his "masterpiece" although it was so expensive that it seriously damaged the finances of Bavaria Film.Noa is perhaps best known today for his 1922 film Nathan the Wise, an adaptation of Gotthold Ephraim Lessing's 1779 play of the same title, which made a plea for religious tolerance.
