Antanas Juška (16 June 1819 – 1 November 1880) was a Lithuanian Roman Catholic priest known for his lifelong study of Lithuanian folk traditions. For about three decades, he observed the Lithuanian people, their traditions, and recorded their songs and vocabulary. Juška recorded about 7,000 Lithuanian folk songs, including about 2,000 songs with melodies, and wrote a 70,000-word Lithuanian–Polish dictionary. These works provide a wealth of information of the 19th-century Lithuanian life. His works were partially published with the help of his elder brother Jonas Juška.
