Tanya Khovanova (Татьяна Гелиевна Хованова, also spelled Tatyana Hovanova; born 25 January 1959) is a Soviet-American mathematician who became the second female gold medalist at the International Mathematical Olympiads.

As a high school student, Khovanova became a member of the Soviet team for the International Mathematical Olympiad (IMO).

In the summer of 1975, Valery Senderov gave the team a list of difficult mathematical problems used in the entrance exams of Moscow State University to discriminate against Soviet Jews, a topic she later wrote about.

Her finish at the 1976 Olympiad was second among all competitors,[2] the highest achievement for female students until 1984, when Karin Gröger from East Germany tied for the first place.

[5] Khovanova has been a mathematics competition coach at the Advanced Math and Science Academy Charter School in Marlborough, Massachusetts.
