Anna Vsevolodovna of Kiev also called Ianka (died 3 November 1112), was a Rus' princess and nun, noted for having introduced schools for girls in Kievan Rus. She was the daughter of Vsevolod I of Kiev and Anastasia. She was engaged to the Byzantine prince Konstantios Doukas in 1074. The marriage never materialized, as Constantine Dukas was forced to become a monk in 1081 and died in 1082 before they could be married.
