Abraham Dov Bär ben David Flahm (Hebrew: אברהם דובערוש בן דוד פלאהם) was the editor and publisher of the Dubner Maggid.
For over 40 years he continued refining his works, while adding his own commentary, and prefaces with the history of the Maggid.
Flahm put a notice in the yearly published Hagada that the original parables were extracted from unintelligible writings, and many times had parts needing completion which he himself had written.
Originals of many of the first publishing of Flahm can be found at the Jewish National and University Library.
It is highly probable that Abraham Dov was family to the Maggid of Lutzk Rabbi Shlomo Flam, the teacher of the Grand Rabbi of Belz and the student of the Maggid of Mezritch.
