Manfred Noa (22 March 1893 – 5 December 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 its production company Bavaria Film.

A film and art director later specialised in historical films, 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. He was the third husband of the actress Eva May, who was the daughter of his fellow director Joe May and actress Mia May. Noa died 5 December 1930 in Berlin of peritonitis.^{[citation needed]}
