Grand Duke Sergei Alexandrovich of Russia /великий князь Сергей Александрович ; 11 May 1857 – 17 February 1905/ was the fifth son and seventh child of Emperor Alexander II of Russia. He was an influential figure during the reigns of his brother Emperor Alexander III of Russia and his nephew Emperor Nicholas II, who was also his brother-in-law through Sergei's marriage to Elizabeth, the sister of Tsarina Alexandra.

Grand Duke Sergei's education gave him lifelong interests in culture and the arts. Like all male members of the Romanov dynasty, he followed a military career, and he fought in the Russo-Turkish War of 1877–78, receiving the Order of St George for courage and bravery in action. In 1882, his brother, Tsar Alexander III, appointed him Commander of the 1st Battalion Preobrazhensky Life Guard Regiment, a position he held until 1891. In 1889, Grand Duke Sergei was promoted to the rank of Major General. In 1884, Sergei married Princess Elisabeth of Hesse and by Rhine, a granddaughter of Queen Victoria. Their marriage remained childless, but they became the guardians of the two children of his brother, Grand Duke Paul Alexandrovich of Russia: Grand Duchess Maria, and Grand Duke Dmitri. Grand Duke Sergei Alexandrovich and his wife promoted the marriage of Sergei's nephew, Tsar Nicholas II, with Princess Alix of Hesse, Elizabeth's youngest sister.
Between 1891 and 1905, Grand Duke Sergei served as Governor-General of Moscow. His reputation was initially tarnished as he was partially blamed for the Khodynka Tragedy during the festivities following the coronation of Emperor Nicholas II. As Governor of Moscow, he pursued very conservative policies that made him a polarizing figure. In 1894 Grand Duke Sergei was made a member of the State Council. In 1896 he was promoted to Lieutenant General and appointed as Commander of Moscow Military District. After thirteen years of service, Grand Duke Sergei resigned from the Governorship on 1 January 1905, though he remained head of the Moscow Military District. Targeted by the SR Combat Organization, he was assassinated later that year by a terrorist bomb at the Kremlin during the 1905 Russian Revolution.
