Rishonim (; ; sing. ראשון, Rishon, "the first ones") were the leading Rabbis and Poskim who lived approximately during the 11th to 15th centuries, in the era before the writing of the Shulchan Aruch (Hebrew: שׁוּלחָן עָרוּך, "Set Table", the code of Jewish law, 1563 CE) and following the Geonim (589-1038 CE). Rabbinic scholars subsequent to the Shulkhan Arukh are generally known as "Acharonim ("the latter ones").
