Mir Brachfeld is an Haredi Jewish yeshiva in the Israeli settlement of Modi'in Illit.

It was founded by Rabbi Nosson Tzvi Finkel as a branch of the Mir Yeshiva in Jerusalem.

Rabbi Aryeh Finkel led the yeshiva until his death in 2016.

Rabbi Aryeh Finkel, a grandson of Mir rosh yeshiva Rabbi Eliezer Yehuda Finkel, who had been giving a shiur in Mir Yerushalayim until then, was appointed rosh yeshiva.

[1] Rabbi Nosson Tzvi remained involved to the yeshiva over the years,[2] sometimes coming for Shabbos, among other things.
