Lajos Bárdos (October 1, 1899 – November 18, 1986) was a composer, conductor, music theorist, and professor of music at the Franz Liszt Academy of Music, in Budapest, Hungary, where he had previously studied under Albert Siklós and Zoltán Kodály. His younger brother, György Deák-Bárdos, was also a composer. The teaching methods that Bárdos developed contributed to what has since come to be known as the Kodály Method of musical training. "Lajos Bárdos Music Week" has been an annual festival in Hungary since 1977.
