Hyacinthe-Marie-Joseph Corne (1802–1887) was a French magistrate and politician who was active during several political regimes in 19th-century France. Born in Arras on August 4, 1802, he pursued a career in law and held various judicial appointments, including serving as a prosecutor (procureur du roi) in Douai.
Corne began his parliamentary career during the July Monarchy, winning election to the Chamber of Deputies for the Nord department in 1837. He was a member of the dynastic opposition, advocating for moderate liberal reforms. Following the Revolution of 1848, he was elected to both the Constituent Assembly and the Legislative Assembly of the Second Republic. During this period, he was noted for his work on judicial committees and his interest in social issues, particularly prison reform and the penitentiary system.
Following the coup d'état of December 2, 1851, Corne largely withdrew from national political life. He returned to the legislature during the Third Republic and was elected as a Life Senator (sénateur inamovible) in December 1875. He held this position until his death in Paris on July 2, 1887. Throughout his career, he authored various legal reports and documents concerning judicial administration and public policy.
