Andrey Nikolayevich Tychonoff (Russian: Андрей Николаевич Тихонов) (October 30, 1906, Gzhatsk – November 8, 1993, Moscow) was a Soviet and Russian mathematician known for important contributions to topology, functional analysis, mathematical physics, and ill-posed problems. Tychonoff originally published in German, whence the transliteration. The English style "Tikhonov" is also commonly seen. Born near Smolensk, he studied at the Moscow State University where he received Ph.D. in 1927 under direction of Pavel Sergeevich Alexandrov.

He became a corresponding member of the USSR Academy of Sciences on 29 January 1939 and a full member of the USSR Academy of Sciences on 1 July 1966. Tychonoff worked in a number of different fields in mathematics. He made important contributions to topology, functional analysis, mathematical physics, and certain classes of ill-posed problems.
