The Cruise of the Kings (Greek: Η κρουαζιέρα των γαλαζοαίματων, romanized: I krouaziéra ton galazoématon, lit. 'The cruise of the blue-bloods') was a royal cruise around the Mediterranean Sea in the summer of 1954, organised by Queen Frederica and King Paul of Greece.
The cruise aimed to promote tourism in Greece and was drafted by Frederica. It occurred from 23 August to 3 September 1954 on the royal yacht Agamemnon. Royals from over 25 reigning and formerly reigning royal families were in attendance. A second cruise was scheduled for August 1956, but the nationalisation of the Suez Canal and its closure by the British government, as well as growing violence in the Levant, prevented the cruise from playing out smoothly. The cruise was transformed into a shorter stay in Mon Repos, Corfu.
