Anna Stepanovna Demidova (26 January 1878 – July 17, 1918) was a maid in the service of Tsarina Alexandra of Russia. She stayed with the Romanov family when they were arrested, and was executed at the same time as Alexandra on July 17, 1918. She had shared the Romanov family's exile at Tobolsk and Ekaterinburg following the Russian Revolution of 1917 before their execution. She is remembered for staying with the Romanovs to the end. In 1981 she was canonized as an Orthodox martyr by the Russian Orthodox Church Outside Russia (ROCOR) but not by the Russian Orthodox Church.
