Sergei Vladimirovich Konyagin (Russian: Серге́й Владимирович Конягин; born 25 April 1957)^[1] is a Russian mathematician. He is a professor of mathematics at the Moscow State University. His primary research interest is in applying harmonic analysis to number theoretic settings.

Konyagin participated in the International Mathematical Olympiad for the Soviet Union, winning two consecutive gold medals with perfect scores in 1972 and 1973. At the age of 15, he became one of the youngest people to achieve a perfect score at the IMO.

In 1990 Konyagin was awarded the Salem Prize.

In 2012 he became a fellow of the American Mathematical Society.^[2]
