Wahasidimu ni kundi la Wayahudi (kwa Kiebrania חסידות, hasidut, kutoka neno lenye maana ya "ibada"). Asili yake ni mwamko wa kiroho katika karne ya 18 ambao kutoka Ukraine magharibi ulienea haraka Ulaya Mashariki kote. Israel Ben Eliezer, "Baal Shem Tov", anahesabiwa kuwa mwanzilishi wake. Leo wafuasi wake ni 400,000 hivi, na wengi wao wako Marekani, Israel na Ufalme wa Muungano. Elior, Rachel (2006). The Mystical Origins of Hasidism. Littman Library of Jewish Civilization.
