This is a list of rulers who converted to Christianity. The conversion of monarchs was often an important step in the process of Christianization.
Gregory the Illuminator was the founder and first official head of the Armenian Apostolic Church. He converted Armenia from Zoroastrianism to Christianity in the early fourth century, making Armenia the first state to adopt Christianity as its official religion. He is venerated as a saint in the Armenian Apostolic Church and in some other churches.
Mieszko I was the first ruler of Poland and the founder of the first independent Polish state, Civitas Schinesghe also known as the Duchy of Poland. His reign stretched from 960 to his death and he was a member of the Piast dynasty, a son of Siemomysł and a grandson of Lestek. He was the father of Bolesław I the Brave and of Gunhild of Wenden. Most sources identify Mieszko I as the father of Sigrid the Haughty, a Scandinavian queen, the grandfather of Canute the Great and the great-grandfather of Gunhilda of Denmark, Canute the Great's daughter and wife of Henry III, Holy Roman Emperor.
Mirian III was a king (mepe) of Iberia or Kartli (Georgia), contemporaneous to the Roman emperor Constantine the Great. He was the founder of the royal Chosroid dynasty.
Saint Nino was a woman who preached Christianity in the territory of Caucasian Iberia, of what is now part of Georgia. It resulted in the Christianization of the royal house of Iberia, with the consequent Christianization of Iberia.
Tiridates III, also known as Tiridates the Great or Tiridates IV, was the Armenian Arsacid king from c. 298 to c. 330. In the early 4th century, Tiridates proclaimed Christianity as the state religion of Armenia, making the Armenian kingdom the first state to officially embrace Christianity.
Mirian I was a king (mepe) of Iberia who reigned in the 2nd century BC. An adopted son of his father-in-law King Sauromaces I, he was a Persian-born prince but governed over Iberia as a member of the Pharnavazid dynasty.
Equal-to-apostles or equal-to-the-apostles is a special title given to some saints in Eastern Orthodoxy and in Byzantine Catholicism. The title is bestowed as a recognition of these saints' outstanding service in the spreading and assertion of Christianity, comparable to that of the original apostles.
The Chosroid dynasty, also known as the Iberian Mihranids, were a dynasty of the kings and later the presiding princes of the early Georgian state of Iberia from the 4th to the 9th centuries. The family, of Iranian Mihranid origin, accepted Christianity as their official religion c. 337, and maneuvered between the Byzantine Empire and Sassanid Iran to retain a degree of independence. After the abolition of the Iberian kingship by the Sassanids c. 580, the dynasty survived in its two closely related, but sometimes competing princely branches—the elder Chosroid and the younger Guaramid—down to the early ninth century when they were succeeded by the Georgian Bagratids on the throne of Iberia.
The Pharnavazid is the name of the first dynasty of Georgian kings of Kartli (Iberia) preserved by The Georgian Chronicles. Their rule lasted, with intermissions, from the 3rd century BC to the 2nd century AD. The main male line is reported to have become extinct early on and followed by houses related to it in the female line. By the close of the 2nd century AD, the Pharnavazid rule came to an end and the Arsacid dynasty took over the crown of Iberia.
Rev II was a prince of Iberia of the Chosroid Dynasty who functioned as a co-king to his father Mirian III, the first Christian Georgian ruler and his mother was Nana of Iberia. Professor Cyril Toumanoff suggests the years 345–361 as the period of their joint reign.

Ashkhen was the Queen of Armenia and a member of the Arsacid dynasty by marriage to King Tiridates III of Armenia.
Salome was an Armenian princess from the Arsacid dynasty who was married into the Chosroid Dynasty of Iberia. She was a daughter of King Tiridates III of Armenia and Queen Ashkhen. She is known from the early medieval Georgian chronicle Life of Kings. In Georgian tradition, she is referred to as Salome of Ujarma after a castle where she is credited to have erected a cross. She has been canonized by the Armenian and Georgian churches. Local canonisations are recognised throughout the Orthodox Church.

The Christianization of Iberia refers to the spread of Christianity in the early 4th century by the sermon of Saint Nino in an ancient Georgian kingdom of Kartli, known as Iberia in classical antiquity, which resulted in declaring it as a state religion by then-pagan King Mirian III of Iberia. Per Sozomen, this led the king's "large and warlike barbarian nation to confess Christ and renounce the religion of their fathers", as the polytheistic Georgians had long-established anthropomorphic idols, known as the "Gods of Kartli". The king would become the main sponsor, architect, initiator and an organizing power of all building processes. Per Socrates of Constantinople, the "Iberians first embraced the Christian faith" alongside the Abyssinians, but the exact date of an event is still debated. Georgian monarchs, alongside the Armenians, were among the first anywhere in the world to convert to a Christian faith. Prior to the escalation of Armeno-Georgian ecclesiastical rivalry and the christological controversies their Caucasian Christianity was extraordinarily inclusive, pluralistic and flexible that only saw the rigid ecclesiological hierarchies established much later, particularly as "national" churches crystallized from the 6th century. Despite the tremendous diversity of the region, the christianization process was a pan-regional and a cross-cultural phenomenon in the Caucasus, Eurasia's most energetic and cosmopolitan zones throughout the late antiquity, hard enough to place Georgians and Armenians unequivocally within any one major civilization. The Jews of Mtskheta, the royal capital of Kartli, that did play a significant role in the Christianization of the kingdom, would give a strong impetus to deepen the ties between the Georgian monarchy and the Holy Land leading to an increasing presence of Georgians in Palestine, as the activities of Peter the Iberian and other pilgrims confirm, including the oldest attested Georgian Bir el Qutt inscriptions found in the Judaean Desert alongside the pilgrim graffiti of Nazareth and Sinai.
