Prince Tomislav of Yugoslavia (; 19 January 1928 – 12 July 2000) was a member of the House of Karađorđević, the second son of King Alexander I and Queen Maria of Yugoslavia. He was a younger brother of King Peter II of Yugoslavia and a former nephew-in-law to Queen Elizabeth II and Prince Philip. Early life and education Prince Tomislav was born on 19 January 1928, on Epiphany according to the Julian calendar used by the Serbian Orthodox Church, at 1 am, as the second son of the sovereign of the then Kingdom of Serbs, Croats and Slovenes (later the Kingdom of Yugoslavia), Alexander I (1888–1934) and Queen Maria (1900–1961), the second daughter of King Ferdinand of Romania (1865–1927) and his wife Queen Marie (1875–1938). He was baptized on 25 January in a salon of the New Palace in Belgrade, with the British Minister to the Yugoslav Court, Kennard, representing the godfather King George V, with water from the Vardar and Danube rivers and the Adriatic Sea. The Prince was named after Tomislav of Croatia, the King of medieval Croatia.

Not long after, Alexander granted them their petition but dropped Tomislav of Croatia from his decree. He began his elementary education at the Belgrade Palace but in 1937 he started to attend Sandroyd School in Cobham, England. He stayed in the UK throughout World War II and after King Peter was deposed, moving on to Oundle School from 1941 to 1946 and Clare College, Cambridge in 1946–1947.
