Prince Nikita Alexandrovich was born in Saint Petersburg at his parents' palace at 106, Moika street.^[1] He was the son of Grand Duke Alexander Mikhailovich of Russia and Grand Duchess Xenia Alexandrovna of Russia. Through his mother he was a grandson of Tsar Alexander III of Russia and his consort, the Tsarina Maria Feodorovna of Russia (born Princess Dagmar of Denmark).

Prince Nikita spent his childhood and adolescence in fabulous splendor under the reign of his uncle, Tsar Nicholas II. He also traveled with his parents through Europe. A favorite destination was Ai-Todor, his father's estate, located in Crimea on the shores of the Black Sea. It was there where Prince Nikita and his immediate family found refuge from the disturbances in the former Imperial capital after the fall of the monarchy in Russia in February 1917. For a time, they lived there undisturbed. Their situation deteriorated after the Bolsheviks rose to power.

Prince Nikita was placed under house arrest with his parents and other members of the Romanov family in Crimea for sometime. He left Russia on 11 April 1919 with the help of his great aunt Queen Alexandra of the United Kingdom (formerly Princess Alexandra of Denmark), a sister of the Dowager Tsarina Maria. King George V sent the British warship HMS Marlborough, which brought Prince Nikita's family and other members of the Romanov dynasty, headed by the Dowager Tsarina Maria Feodorovna, from the Crimea over the Black Sea to Malta and then to England.

During his first years in exile, Prince Nikita lived in Paris in the house of his sister Princess Irina Alexandrovna of Russia. He moved later to England where he graduated from Oxford University. During his student years, Prince Nikita was president of the Oxford University Russian Club.^[2]
