Lev Avnerovich Leviev (born July 30, 1956 in Tashkent, USSR) is a Bukharian-Israeli billionaire businessman, with a net worth of roughly $12 billion following the 2008 global financial crisis. Leviev is one of the most prominent Mizrahi Jewish individuals in the world and has been a major philanthropist for Jewish causes in Eastern Europe and Israel. His diamond mining investments in Angola and his investments in Israeli settlements have been the target of protests.

Leviev was born in Tashkent, Uzbek SSR in 1956, and today lives in London and Israel. His parents, Avner and Chana Leviev, were prominent members of the Bukharian Jewish community, and Leviev practises Chabad Sephardic Judaism. In 1971, when he was fifteen, his family emigrated from Uzbekistan to Israel. Shortly afterwards, Leviev began to work as an apprentice in a diamond polishing plant, learning the 11 steps of the diamond cutting process. After serving in the Israel Defense Forces, he established his own diamond polishing plant.
