This list of royal saints and martyrs enumerates Christian monarchs, other royalty, and nobility who have been beatified or canonized, or who are otherwise venerated as or conventionally given the appellation of "saint" or "martyr". Their names are in English and, where known, in their own language. When the status of a nominee is dubious the whole entry is italicized. Popes are not included in this list, unless they came from nobility themselves. Although they may be considered sovereigns, a list of Papal Saints is enumerated elsewhere.

Biblical royal saints

Melchizedek, the King of Salem, is venerated as a Saint and appears to be among the earliest Royalty in the Bible. Joseph is venerated as a Saint, within Christianity, with one apocryphal text (Joseph and Asenath) suggesting he may have even become Pharaoh after his work as Vizier in Egypt. Moses is also considered to have been saved, and is sometimes thought to have been a member of the Egyptian Royal family. King David of the Biblical Kingdom of Israel and his successors Hezekiah and Josiah of the southern Kingdom of Judah are traditionally considered to be Saints by Catholic teaching. In the New Testament genealogies, Jesus Christ is a descendant of King David and has been proclaimed by the Catholic Church as King of the Universe. His mother, Mary, is also celebrated within Catholic teaching as Queen of Heaven. Within tradition, she too is a descendant of King David, as were both her parents - Sts. Joachim and Anne. Medieval traditions would include within this number some of the Apostles, as part of a broader kinship to Christ.
