Anne-Marie (August 30, 1946) is a Greek and Danish royal who was Queen of Greece as the consort of King Constantine II from their marriage in 1964 until 1973.
Born Princess Anne-Marie of Denmark, she is the third and youngest daughter of King Frederick IX of Denmark and his wife Ingrid of Sweden.
Anne-Marie married King Constantine II when she was only 18 years old, in 1964, and became queen consort of Greece. They had five children: Princess Alexia, Crown Prince Pavlos, Prince Nikolaos, Princess Theodora, and Prince Philippos. As queen, Anne-Marie spent much of her time working for a charitable foundation known as "Her Majesty's Fund" and later as the "Anne-Marie Foundation", which provided assistance to people in rural areas of Greece. In 1967, however, the royal family were forced into exile, and Constantine was later deposed as Greece transitioned into a republic.
She is the youngest sister of Queen Margrethe II of Denmark.
On January 10, 2023, Anne-Marie was widowed when her husband died of a stroke at the private Hygeia Hospital in Athens at the age of 82.
