Hyacinthe de Valroger, CO (6 January 1814, at Caen – 10 October 1876), was a French Catholic priest and Oratorian.
As a young man, Valroger first studied medicine, but later entered the seminary and was ordained a priest in 1837, after which he made Director of the minor seminary of Bayeux.
In 1852 he joined Joseph Gratry in the work of restoring the French Oratory, where he became professor of theology, Master of novices and assistant Superior General.
De Valroger believed that the theory of evolution could be reconciled with the Book of Genesis.
He argued against the idea of abiogenesis, claiming that there was an intervention of "intelligence" (which he equated with God) acting upon the organization of living matter.
