Maxime Jacob, or Dom Clément Jacob, (13 January 1906, Bordeaux – 26 February 1977, Abbaye En-Calcat, Dourgne, Tarn) was a French composer and organist.
Jacob studied at the Paris Conservatory with Charles Koechlin and André Gedalge; an admirer of Darius Milhaud and Erik Satie, he was a member of the Ecole d'Acueil. In 1929, Jacob converted from Judaism to Catholicism (influenced by Jacques Maritain) and became a Benedictine monk. He would go on to study organ with Maurice Duruflé, as well as Gregorian chant.
Jacob also published two books, L'art et la grâce (1939) and Souvenirs a deux voix (1969).
In the Anglosphere, his hymn tune "Living God" in 77.77 meter with 77.77 refrain, used for I Received the Living God (J'ai reçu le Dieu vivant), is well known.
