Jewish Renewal (Hebrew: התחדשות יהודית, romanized: Hitḥadeshut Yehudit) is a Jewish religious movement originating in the 20th century that endeavors to reinvigorate modern Judaism with Kabbalistic, Hasidic, and musical practices. Specifically, it seeks to reintroduce the "ancient Judaic traditions of mysticism and meditation, gender equality and ecstatic prayer" to synagogue services. It is distinct from the baal teshuva movement of "return" to religious observance of Orthodox Judaism.

The term "Jewish Renewal" describes "a set of practices within Judaism that attempt to reinvigorate what it views as a moribund and uninspiring Judaism with mystical, Hasidic, musical and meditative practices drawn from a variety of traditional and untraditional, Jewish and other, sources. In this sense, Jewish Renewal is an approach to Judaism that can be found within segments of any of the Jewish denominations".

The term also refers to an emerging Jewish movement, the Jewish Renewal movement, which describes itself as "a worldwide, transdenominational movement grounded in Judaism's prophetic and mystical traditions". The Jewish Renewal movement incorporates social views such as egalitarianism, environmentalism and pacifism.

Jewish Renewal rabbi Barbara Thiede writes:

Jewish Renewal will joyfully embrace music, meditation, chant, yoga, and storytelling in the practice of Judaism. Jewish Renewal reads Torah as our deepest challenge and our most precious gift ... Jewish Renewal is about learning the why and not just the how. It's about plumbing the very depths of why so that we can hear our private and godly voices of truth ... Ideas, texts, tradition – Jewish understanding laced together in a sweet web of life so clearly that I could unpack the teaching as easily as I could unzip a boot.

The movement's most prominent leader was Zalman Schachter-Shalomi. Other leaders, teachers and authors associated with Jewish Renewal include Arthur Waskow, Michael Lerner, Tirzah Firestone, Phyllis Berman, Shefa Gold, David Ingber, and Marcia Prager.

Jewish Renewal brings kabbalistic and Hasidic theory and practice into a non-Orthodox, egalitarian framework, a phenomenon sometimes referred to as neo-Hasidism. Like Hasidic Jews, Renewal Jews often add to traditional worship ecstatic practices such as meditation, chant and dance. In augmenting Jewish ritual, some Renewal Jews borrow freely and openly from Buddhism, Sufism and other faiths.

Jewish Renewal, in its most general sense, has its origins in the North American Jewish countercultural trends of the late 1960s and early 1970s. During this period, groups of young rabbis, academics and political activists founded experimental chavurot (singular: chavurah) or "fellowships" for prayer and study, in reaction to what they perceived as an over-institutionalized and unspiritual North American Jewish establishment.
