Denikina, who was born in 1919 in southern Russia, died overnight in Paris, where her family had originally settled after emigrating.
She was the daughter of General Anton Denikin, a celebrated Tsarist general who, after the 1917 Bolshevik revolution, led forces opposing the Bolsheviks on the southern front during the civil war. He died in the United States in 1947 but his remains were reburied in Moscow on 3 October 2005, in accordance with his wishes that he be reburied in Russia once the Soviet Union no longer exists.
Denikina was granted Russian citizenship earlier this year. At the time, she told RFE/RL that she "wanted to die a Russian citizen."
Russian media said she will be buried in Paris.
