Adolphe Biarent (16 October 1871 – 4 February 1916) was a Belgian composer, conductor, cellist and music teacher.
Biarent studied at the conservatories of Brussels and of Ghent, and was a pupil of Émile Mathieu.
He won a Belgian Prix de Rome with his cantata Oedipe à Colone in 1901, after which he remained near his home in Charleroi, composing, conducting and teaching (or more accurately, engaging in pedagogy, for example the writing of manuals as well).
