Sadigura is a Hasidic dynasty, one of the branches of the Ruzhiner dynasty. The dynasty began with Rabbi Avrohom Yaakov Friedman of Sadigura now located in Ukraine, who was a son of the Holy Rabbi Israel Friedman of Ruzhin, the founder of the Ruzhiner dynasty. Today the Sadigura Hasidism is centered on the Sadigurer Rebbe's beis medrash in Bnei Brak, Israel.
