Haggahot Maimuniyyot (Hebrew: הגהות מיימוניות) is a 13th-century halakhic work authored by Meir HaKohen.
The work consists of supplemental notes (haggahot) to the Mishneh Torah of Maimonides, with the objective of imparting contemporary Sephardic thought to Jews in Germany and France, while juxtaposing it to contemporary Ashkenazi halakhic customs.
[1] The work may originally have been written on the margins of the Mishneh Torah, as it appears in early manuscripts.
The second, called "Teshovot Maimuniyyot", is appended at the end of each book and contains responsa by German and French scholars relevant to the topics in the body of the work.
The work as a whole constitutes an important source for Medieval Ashkenazi rabbinic literature, containing a number of attributed formulations that appear nowhere else.
