Prince Don Bagrat de Bagration y de Baviera, also Prince Bagrat Bagrationi-Mukhraneli and Prince Bagrat Bagration-Moukhransky (12 January 1949 – 20 March 2017) was a member of the Bagration dynasty which once ruled the Kingdom of Georgia in the Caucasus and a relative of the royal family of Spain.

He was born in Madrid, Spain on 2 February 1949 and named Bagrat Juan María de Fátima de Todos los Santos, the third child of Prince Irakli Bagration-Mukhrani (1909-1977) by his third wife, Infanta Doña María de las Mercedes de Baviera y Borbón (1911-1953), a niece of King Alphonso XIII. His godparents were Don Juan and Princess Doña Mercedes de Borbón-Dos Sicilias y Orléans, Count and Countess of Barcelona. His maternal great-grandfather was King Alfonso XII. Prince Jorge de Bagration, a Spanish race car driver and pretender to the throne of Georgia, was his elder half brother.

Although born in Tbilisi, his father left Georgia after completing his studies there, lived briefly in Italy and France, but acquired Spanish citizenship in 1947. His mother had been born in Madrid, and although part of her youth was spent in exile in the Basses Pyrenees of France, Bagrat was raised, along with Jorge and his elder sister Princess Mariam (born 1947), by his widowed father in Madrid and at the Palacio de Santillana del Mar in Santander.

He was a knight of the Sovereign Military Order of Malta (Spanish association, No. 21658 as decreed in the Magisterial Palace of Rome on 31 January 1980).
