Lev Mordukhov Tseitlin (Лев Цейтлин 1884, in Pinsk – July 8, 1930, in New York City), billed as Leo Zeitlin, was a Russian composer. In 1923, he emigrated to the United States. His best-known work is Eli Zion, a paraphrase for piano and cello "on a folk theme and trope of 'Song of Songs'". Zeitlin was a violinist, violist, conductor and impresario who was active in Saint Petersburg's Society for Jewish Folk Music. In 1923, shortly after he arrived in New York City with his wife Esther from the Free City of Danzig, he became the violist and arranger for the Capitol Theatre.
