Jacques Paul Migne (; 25 October 1800 – 24 October 1875) was a French priest who published inexpensive and widely distributed editions of theological works, encyclopedias, and the texts of the Church Fathers, with the goal of providing a universal library for the Catholic priesthood.

The Patrologia Latina and the Patrologia Graeca (along with the Monumenta Germaniae Historica) are among the great 19th century contributions to the scholarship of patristics and the Middle Ages. Within the Roman Catholic Church, Migne's editions put many original texts for the first time into the hands of the priesthood.

Biography

Migne was born in Saint-Flour, Cantal and studied theology at the University of Orléans. He was ordained in 1824 and placed in charge of the parish of Puiseaux, in the diocese of Orléans, where his uncompromisingly Catholic and royalist sympathies did not coincide with local patriotism and the new regime of the Citizen-King. In 1833, after falling out with his bishop over a pamphlet he had published, he went to Paris, and on 3 November started a journal, , Despite his insurance contracts, Migne was only able to retrieve a pittance.

Shortly afterwards, Georges Darboy, Archbishop of Paris, forbade the continuance of the business and even suspended Migne from his priestly functions. The Franco-Prussian War of 1870 inflicted further losses. Then from the curia of Pope Pius IX came a decree condemning the use of Mass stipends to purchase books, which specifically called out Migne and his publications.

Migne died in Paris. He died without ever regaining his former success and his passed in 1876 into the hands of Garnier Frères.
