Chief town in the department of the Yonne (the ancient Champagne), France, situated on the River Yonne. It had an important Jewish community, which flourished especially in the twelfth century. The "notables of Joigny" are mentioned in the Maḥzor Vitry (No. 244). The rabbis of this place were reckoned among the most important of France; e.g., Menahem ben Perez (died toward the end of the twelfth century) and Yom-Ṭob ben Isaac, surnamed "the Holy," i.e., the martyr, who died at York, England, in 1190.
