Jean-Marie Bienaimé Bonnassieux (French pronunciation: [ʒɑ̃ maʁi bɔnasjø]; 1810, Panissières, Loire – 1892) was a French sculptor.

Born the son of a cabinet maker in Lyon, Bonnassieux exhibited talent from a young age.He received his education at the École nationale supérieure des Beaux-Arts in Paris under the guidance of Augustin-Alexandre Dumont. In 1836, he shared the Prix de Rome with Auguste Ottin, after which he continued his studies in Rome under the tutelage of Ingres.

Subsequently, Bonnassieux became a teacher at the Ecole. Among his pupils in the 1880s were the young American Lorado Taft and the British-American sculptor Henry Hudson Kitson. A study by A. Le Normand, La Tradition Classique et l'Esprit Romantique: Les sculpteurs de l'académie de France à Rome de 1824 à 1840 (Rome, 1991), places Bonnassieux within the context of the rigorous French academic training of the 19th century, examining the careers of seventeen winners of the Prix de Rome.

Bonnassieux is buried at Montparnasse Cemetery.
