Alfred Ottokar Lorenz (July 11, 1868, Vienna - November 20, 1939 Munich) was an Austrian-German conductor, composer, and musical analyst. His principal work is the four-volume Das Geheimnis der Form bei Richard Wagner, which attempts to comprehensively analyze some of Richard Wagner's best-known operas. Lorenz's work reflects to a great extent his sympathy with Nazi ideology, and has only recently been discredited by scholarship.
