André Hajdu (Hungarian: Hajdú András; Hebrew: אנדרה היידו; 5 March 1932 – 1 August 2016) was a Hungarian-born Israeli composer and ethnomusicologist.

Hajdu studied at the Franz Liszt Academy of Music in Budapest with Endre Szervánszky and Ferenc Szabó (composition), Erno Szégedi (piano), and Zoltán Kodály (ethnomusicology).

As a Kodály disciple, he was involved for two years in research about Gypsy musical culture and published several articles on this subject.

[2] Among his class mates were Gilbert Amy, William Bolcom, Philip Corner and Paul Méfano.

Hajdu composed many pedagogical works, particularly for piano and theory through a creative approach (involving the player to the process of composing) e.g. Milky Way, Art of Piano-playing, Book of Challenges, Concerto for 10 young pianists.
