Pavlos, Crown Prince of Greece, Prince of Denmark, (; born 20 May 1967), is the second child and eldest son of Constantine II, the last King of Greece from 1964 to 1973, and Anne-Marie of Denmark. Following the death of his father on 10 January 2023, he became head of the former Greek royal family. He was heir apparent to the throne of Greece and was its crown prince from birth, remaining so during his father's reign until the monarchy's abolition. As a male-line descendant of Christian IX of Denmark, he is also a Danish prince although not in succession to its throne. Early life Pavlos was born on 20 May 1967 at the Tatoi Palace north of Athens, used at the time as the secondary residence of the Greek royal family. He was the second child and first son of King Constantine II and Queen Anne-Marie of Greece. In traditional Greek naming practices, first sons were most often named after their paternal grandfathers.

In December of that year, King Constantine attempted a counter-coup that failed due to planning mistakes, leaks, and insufficient military support. Pursued by the junta, the King fled with his wife, children, mother and sister to Rome. From Rome, they went on to Copenhagen, and lived with Queen Anne-Marie's mother, Queen Ingrid. During the years 1967–1973, Greece remained officially a monarchy, with a regency appointed while the King lived in exile. Following the discovery and suppression of a "wide-ranging" anti-junta movement, just before its outbreak, among the ranks of the mostly royalist Navy, Papadopoulos, on 1 June 1973, declared Greece a Presidential Republic with himself as president and proclaimed a
