Meir HaKohen[1] was a German rabbinical scholar of the end of the thirteenth century. He authored Hagahot Maimuniot[1] (or Haggahot Maimuniyyot) (הגהות מיימוניות, abbreviated הגהמי"י) on Maimonides' Mishneh Torah. Giulio Bartolocci[2] mistakenly identifies him with Meïr Ha-Kohen, a French scholar of the same century. He was a student of Meir of Rothenburg.[3]
Hagahot Maimuniot, authored by Meir HaCohen, is one of the most important sources for the halachic rulings of medieval Ashkenazi rabbis. It takes the form of a running commentary on the Mishneh Torah by Maimonides, and nowadays commonly appears at the bottom of the page in many printed editions of Mishneh Torah. There is also a section entitled Teshuvot Maimuniot which appears at the end of each book of Mishneh Torah.[3]
