Jarmil Michael Burghauser (born Jarmil Michael Mokrý; 21 October 1921, Písek – 19 February 1997, Prague) was a Czech composer, conductor, and musicologist.
Burghauser's parents were painters František Viktor Mokrý and Zdenka Burghauserová. He studied piano since he was 6 years old under Jaroslav Křička and later Otakar Jeremiáš. He continued his musical education by studying composition with Václav Talich at Prague Conservatory. From 1948 to 1953 Burghauser was a choirmaster in National Theatre.
After the short-lived Prague Spring, he incurred the disfavor of his country's Communist regime and had to adopt the pseudonym Michal Hájků in order to write a series of compositions in a style which evoked earlier periods of music, called Storia apocrifa della musica Boema.
