Leontovych was born and raised in the Podolia province of the Russian Empire (now in Ukraine). He was educated as a priest in the Kamianets-Podilskyi Theological Seminary and later furthered his musical education at the Saint Petersburg Court Capella and private lessons with Boleslav Yavorsky. With the independence of the Ukrainian state in the 1917 revolution, Leontovych moved to Kyiv where he worked at the Kyiv Conservatory and the Mykola Lysenko Institute of Music and Drama. He is recognised for composing "Shchedryk" in 1904 (which premiered in 1916), known to the English-speaking world as "Carol of the Bells" or "Ring, Christmas Bells". He is known as a martyr in the Eastern Orthodox Ukrainian Church, where he is also remembered for his liturgy, the first liturgy composed in the vernacular, specifically in the modern Ukrainian language. He was assassinated by a Soviet agent in 1921.
