James Victor Uspensky (born April 29, 1883 in Urga , Mongolia , † January 27, 1947 in San Francisco ) was a Russian-born American mathematician.

Uspensky studied at the University of Saint Petersburg , where he graduated in 1906 and received his doctorate in 1910 (Russian doctorate, equivalent to habilitation). From 1912 he was a private lecturer in Saint Petersburg and from 1915 to 1923 professor. In the 1920s he went to the USA, but he did not need to flee, he used an officially approved and financed trip abroad. From 1929 he was a professor at Stanford University , where he received a permanent professorship in 1931 and remained until his death. At Stanford he was a colleague of George Pólya .

Uspensky dealt with number theory, probability theory and analysis. He independently published the asymptotic formula for the partition function by S. Ramanujan and Godfrey Harold Hardy (1918) in 1920 .

From 1921 he was a member of the Russian Academy of Sciences .

Ivan Matwejewitsch Vinogradov was one of his students in St. Petersburg .
