Aharon Dolgopolsky (Hebrew: אהרון דולגופולסקי, Russian: Арон Борисович Долгопольский; 18 November 1930 – 20 July 2012) was Russian- Israeli linguist and one of the modern founders of comparative Nostratic linguistics.
Born in Moscow, he arrived at the long-forgotten Nostratic hypothesis in the 1960s, at around the same time but independently of Vladislav Illich-Svitych. Together with Illich-Svitych, he was the first to undertake a multilateral comparison of the daughter-languages Nostratic. Teaching Nostratics at Moscow University for 8 years, Dolgopolsky moved to Israel in 1976, and taught at the University of Haifa.
He died in Haifa.
