List of converts to Judaism

This article lists nations, groups, or tribes, as well as notable individuals, who have converted to Judaism. This article does not distinguish between Jewish religious movements, which hold different views on the legitimacy of one another's conversion methods. Converts are called gerei tzedek (Hebrew: גֵּרֵי צֶדֶק, romanized: gērê ṣedeq, lit. 'righteous foreigners'; sing. גֵּר צֶדֶק, gēr ṣedeq).

A number of prominent celebrities, such as Madonna, Demi Moore, and Ariana Grande, have become followers of a "New Age" version of Kabbalah (via, e.g., the Kabbalah Centre), derived from the body of Jewish mystical teachings known as Kabbalah, but do not consider themselves—and are not considered—Jewish by the normative Jewish community.
