George, Duke of Mecklenburg (German: Georg Herzog zu Mecklenburg; 5 October [O.S. 22 September] 1899 – 6 July 1963) was the head of the House of Mecklenburg-Strelitz from 1934 until his death. Through his father, he was a direct descendant (great-great-grandson) of Russian Emperor Paul I.

He was born in Oranienbaum, Russia as Count George of Carlow; he was the youngest child and only son of Duke George Alexander of Mecklenburg (6 June 1859 - Saint Petersburg, 5 December 1909) and his morganatic wife (m. Remplin, 6 June 1889) Nataliya Fyodorovna Vonlar-Larskaya, Countess of Carlow (Saint Petersburg, 16 May 1858 - Cannes, 14 March 1921), daughter of Fyodor Ardalionovich Vonlar-Larsky (Dagoutze Chavli, Georgia, 23 December 1835 - 2 February 1903) and wife Mariya Fyodorovna Uvarova, and granddaughter of Ardalion Alexeievich Vonlar-Larsky, born in Poretchie, near Smolensk, and wife Tatyana, daughter of Mariya Mikhailovna Litvinova. Because his parents marriage was morganatic, at birth he was denied the title Duke of Mecklenburg; instead his title came from his mother, who had been created Countess of Carlow on 18 March 1890 by her husband's uncle Grand Duke Friedrich Wilhelm of Mecklenburg-Strelitz. When his father died in 1909, his uncle Duke Charles Michael was appointed guardian of George and his sisters Katharina, Marie and Natalia by Grand Duke Adolf Friedrich V of Mecklenburg-Strelitz. After the 1917 October Revolution George and his family fled Russia heading first to France before later moving to Germany.
