Grand Duke George Mikhailovich of Russia (, also spelled Romanoff; ; born 13 March 1981) is the heir apparent to Maria Vladimirovna, a claimant to the disputed Headship of the Imperial Family of Russia. He is the only child of Maria and her former husband, Prince Franz Wilhelm of Prussia. George's mother attributes to him the title of Tsesarevich and he bears, as a title of pretence, the prefix of "Grand Duke" with the style of Imperial Highness which is still being questioned. As the son of a cadet member of the branch of the House of Hohenzollern which formerly ruled the German Empire and Kingdom of Prussia, he is also sometimes entitled "Prince of Prussia" with the style of Royal Highness.

This response was ignored by Grand Duke Vladimir as he had already selected his daughter to succeed him according to the Pauline laws, and because the marriage between her and Prince Franz Wilhelm of Prussia was deemed dynastic. Prior to their wedding, the Grand Duke and his first cousin, then Head of the House of Hohenzollern, Prince Louis Ferdinand of Prussia, had made a dynastic agreement that any child born from this marriage should be raised as a Romanov. Therefore, George is considered a dynast of both houses (Romanov and Hohenzollern), as his father has never renounced his Prussian royal title. His father, who stopped using his Russian title after his separation, has said
