Alexander Koshetz (12 September 1875 – 21 September 1944) was a Ukrainian choral conductor, arranger, composer, ethnographer, writer, musicologist, and lecturer. He helped popularize Ukrainian music around the world. His name is sometimes transliterated as Oleksandr Koshyts (Ukrainian: Олександр Кошиць).At one time, a performance of Koshetz's Ukrainian National Chorus held the world record for audience attendance, excluding sporting events. His performance also popularized Mykola Leontovych's "Shchedryk" in his concert, which Peter Wilhousky later translated into the popular "Carol of the Bells".
