François Andrieu was a composer, most likely French, of the late 14th century. Nothing is known about him except that he wrote an elegy on the death of Guillaume de Machaut (1377), a four-voice ballade Armes amours / O flour des flours, which is contained in the Chantilly Codex. He also may be tentatively identified as the Magister Franciscus, composer of two other ballades from approximately the same time, though the link can only be made by stylistic similarities.
His music belongs to that portion of late medieval musical practice known as the ars nova.
