Frédéric Labadie-Lagrave (16 August 1844 – 1917) was a French physician who made important contributions to medical literature.

Born at Nérac (department of Lot-et-Garonne), Labadie-Lagrave studied medicine in Paris. During the Franco-Prussian War, while still a resident, he saved a large convoy and was decorated on the battleground at Metz. He took his doctor's degree in 1873. In 1879 he became médecin des hôpitaux in Paris, practicing notably at the Charité hospital.^[1]

With Germain Sée (1818–1896), Labadie-Lagrave wrote the multi-volume Médecine clinique, to which he made extensive contributions on urology and diseases of the liver, kidneys and bile ducts.^[1] Sée's lectures on the diagnostic and treatment of heart diseases were published under his care.

With Felix Legueu (1863–1939), he published Traité médico-chirurgical de gynécologie, an influential book on medical-surgical gynecology. He also contributed numerous articles to Sigismond Jaccoud's Nouveau dictionnaire de médecine et de chirurgie pratiques (for example, articles on gout, hydrophobia, meninges, nerves).^{[citation needed]}

Labadie-Lagrave translated the first American treatise about neurology, W. A. Hammond's Diseases of the nervous system, C. A. Wunderlich's pioneer German book on body temperature Das Verhalten der Eigenwärme in Krankheiten and Siegmund Rosenstein's Die Pathologie und Therapie der Nierenkrankheiten.^[2][3] He retired in 1909.
