List of kings of Greece in the context of "Third Hellenic Republic"

Basileus (Ancient Greek: βασιλεύς) is a Greek term and title that has signified various types of monarchs throughout history. In the English-speaking world, it is perhaps most widely understood to mean 'monarch', referring to either a 'king' or an 'emperor'. The title was used by sovereigns and other persons of authority in ancient Greece (especially during the Hellenistic period), the Byzantine emperors, and the kings of modern Greece. The name Basileios (Basil), deriving from the term basileus, is a common given name in the Eastern Orthodox Church and Syriac Orthodox Church for the Maphrian.

The feminine forms are basileia (βασίλεια), basilissa (βασίλισσα), basillis (βασιλίς), or the archaic basilinna (βασιλίννα), meaning 'queen' or 'empress'. The related term basileia (βασιλεία) has meanings such as 'sovereignty', 'royalty', 'kingdom', 'reign', 'dominion' and 'authority'.

Princess Alexia of Greece and Denmark (Greek: Αλεξία Ντε Γκρες, romanized: Alexía de Grèce; born 10 July 1965) is the eldest child of Constantine II and Anne-Marie, who were King and Queen of Greece from 1964 until the abolition of the monarchy in 1973. She was heiress presumptive to the Greek throne from her birth in 1965 until the birth of her brother Crown Prince Pavlos in 1967.

Pavlos, Crown Prince of Greece, Prince of Denmark (Greek: Παύλος Ντε Γκρες, romanized: Pavlos de Grèce; born 20 May 1967), is a Greek financier who is the former heir apparent to the defunct throne of Greece, becoming the Head of the Royal House of Greece upon his father's death on 10 January 2023. Pavlos was Crown Prince of Greece and heir apparent to the Greek throne from birth until the monarchy's abolition.

Pavlos was born in Athens as the second child and eldest son of the last King of Greece, Constantine II, and his wife Queen Anne-Marie. Pavlos was born into an unstable era for Greek politics, just shy of turning eight months old when he and his family were sent into exile, after Constantine II staged a failed counter-coup against the military junta. They first lived in Rome, before eventually settling in Copenhagen, where his family lived with Pavlos's maternal grandparents, King Frederik IX and Queen Ingrid of Denmark. Although they were in exile since December 1967, his parents continued to officially reign as King and Queen of the Hellenes from 1967 until 1973, when the military junta abolished the Greek monarchy and established the Third Hellenic Republic as its successor state. Following the abolition of the monarchy, Pavlos and his siblings grew up in London.

Prince Nikolaos of Greece and Denmark (Greek: Νικόλαος Ντε Γκρες, romanized: Nikólaos de Grèce; born 1 October 1969) is the third child of Constantine II and Anne-Marie, who were the last King and Queen of Greece, from 1964 to 1973.

Prince Philippos of Greece and Denmark (Greek: Φίλιππος Ντε Γκρες, romanized: Phílippos de Grèce; born 26 April 1986) is the youngest child of Constantine II and Anne-Marie, who were the last King and Queen of Greece, from 1964 to 1973.

The Greek royal family (Greek: Βασιλική Οικογένεια της Ελλάδος) was the ruling family of the Kingdom of Greece from 1863 to 1924 and again from 1935 to 1973. The Greek royal family is a branch of the Danish royal family, itself a cadet branch of the House of Glücksburg. The family had replaced the House of Wittelsbach that previously ruled Greece from 1832 to 1862. The first monarch was George I of Greece, the second son of King Christian IX of Denmark. The current head of the family is former Crown Prince Pavlos, who assumed the role on 10 January 2023 upon the death of his father, former King Constantine II.

With the 1974 Greek republic referendum and Article 4 of the Constitution of Greece, all family members have been stripped of their honorific titles and the associated royal status. Many family members born after 1974 still use the titles "Prince of Greece" and "Princess of Greece" to describe themselves, but such descriptions are neither conferred nor legally recognised by the Greek state as royal or noble titles. The family accepts that these terms are not royal titles, but rather personal identifiers.
