Adam Bahdanovic (Belarusian: ???? ???????? ??????????; Russian: ???? ???????? ??????????; March 25, 1862, Chalopienicy – April 16, 1940, Yaroslavl) was a Belarusian ethnographer and collector of folklore.
Born in a peasant family, he graduated from a pedagogical college in Nyasvizh in 1882 and worked as a school teacher in Minsk and, later, as a bank clerk in Hrodna.
While still in college, Bahdanovic started recording folk tales, songs, and customs, first for the folklorist Pavel Shejn, and eventually as an independent researcher.
His work influenced his son, the poet Maksim Bahdanovic, who frequently turned to folk fairy stories for inspiration.
Adam Bahdanovic was a longtime friend of Maksim Gorki, and wrote several memoir pieces about him.
Bahdanovic's personal library is now a part of the library of Belarusian Academy of Sciences
