Tzadik is a title in Judaism given to people considered righteous, such as biblical figures and later spiritual masters. The root of the word ṣadiq, is ṣ-d-q, which means "justice" or "righteousness". When applied to a righteous woman, the term is inflected as tzadika/tzaddikot.

The Hasidic development of the tzadik combined the former roles of private mystic and social Maggid into communal mystical leadership. Hasidic thought internalised the Ayin-Yesh Heavenly duality of Kabbalah into a complete paradigm for Deveikut perception of Divine Omnipresence. The Hasidic tzadik embodied this as a channel for the Divine flow.[citation needed]
A Rebbe or Admor is the spiritual leader in the Hasidic movement, and the personalities of its dynasties. The titles of Rebbe and Admor, which used to be a general honor title even before the beginning of the movement, became, over time, almost exclusively identified with its Tzadikim.
