Friedrich Wilhelm Stein (17 December 1879 – 14 November 1961) was a German theologian, conductor, musicologist and church musician.
He found in an archive in Jena the score of the so-called Jena Symphony, which he published as possibly a work by the young Ludwig van Beethoven.
After a long period in Kiel from 1919 to 1933, teaching at the Kiel University and as Generalmusikdirektor, he had a leading position in the Reichsmusikkammer of the Nazis in Berlin.
