Étienne Marie Justin Victor Delbos (26 September 1862, Figeac – 16 June 1916, Paris) was a Catholic philosopher and historian of philosophy.
Delbos was appointed a lecturer at the Sorbonne in 1902. In 1911 he became a member of the Académie des Sciences Morales et Politiques. He died in July 1916 as a result of an infectious myocarditis brought on by pleurisy. Maurice Blondel, a close friend, wrote an obituary account of Delbos and saw various posthumous publications through the press.He wrote on Spinoza, Nicolas Malebranche and Kant. A series of lectures on post-Kantian philosophy, which Delbos viewed as shaped by contingent psychological and social factors rather than through the unfolding of some internal logic, were published posthumously and later (1942) collected in a single volume.Delbos was the father of the violinist and composer Claire Delbos. In turn, he was the father-in-law of Olivier Messiaen.
