František Bartoš (16 March 1837 - 11 June 1906) was a Moravian ethnomusicologist, folklorist, folksong collector, and dialectologist. He is viewed as the successor of František Sušil, the pioneer of Moravian ethnomusicology. He notably organized the collecting, categorizing and editing of hundreds of Moravian folksongs which were published is a four volume collection along with about 4000 folksongs from other ethnic traditions. The folksongs appear in ethnographic monographs and the work as a whole is viewed as one of the most important folk song collections ever published. However, Bartoš, like many other early European folk music scholars, sometimes changed the texts of the folk songs, thereby reducing the documentary value of the work.
