Yuri Valentinovich Nesterenko (Russian: Ю́рий Валенти́нович Нестере́нко; born 5 December 1946 in Kharkov, USSR, now Ukraine) is a Soviet and Russian mathematician who has written papers in algebraic independence theory and transcendental number theory.

In 1997, he was awarded the Ostrowski Prize for his proof that the numbers π and e^π are algebraically independent.^[1] In fact, he proved the stronger result:

• the numbers π, e^π, and Γ(1/4) are algebraically independent over Q.
• the numbers π, ${\displaystyle e^{\pi {\sqrt {3}}}}$, and Γ(1/3) are algebraically independent over Q.
• for all positive integers n, the numbers π, ${\displaystyle e^{\pi {\sqrt {n}}}}$ are algebraically independent over Q.

He is a professor at Moscow State University, where he completed the mechanical-mathematical program in 1969, then the doctorate program (Soviet habilitation) in 1973, and became a professor of the Number Theory Department in 1992.

He studied under Andrei Borisovich Shidlovskii. Nesterenko's students have included Wadim Zudilin.
