Denis Bérardier (1735–1794) was a French priest and theologian. He was born at Quimper, in Brittany 26 March 1735 and died at Paris 1 May 1794. He was one of the deputies from the Paris clergy to the Estates-General of 1789.
Bérardier was raised by his grandfather Pierre Bousquet, who had been the founder of the Quimper pottery in 1708. He attended the Jesuit college at Quimper, and then the Sorbonne, where he obtained a doctorate in theology. After the expulsion of the Jesuits from France in 1762, he was appointed Principal of the college at Quimper. He was interested in physics, conducting researches into electricity and founding a physics class at the college.
Bérardier was not on good terms with Toussaint Francois Joseph Conen of St. Luke, the new Bishop of Cornouaille, whose seat was in Quimper and who asserted jurisdiction over the college. He therefore obtained a transfer in 1778 to the extremely prestigious Lycée Louis-le-Grand in Paris, also formerly run by the Jesuits; he also was one of the syndics of the Paris Faculty of Theology. Among his students were Camille Desmoulins and Maximilien Robespierre,
In 1789, when King Louis XVI was forced to summon the Estates-General, he was elected as one of the representatives of the Paris clergy to the Second Estate. When the Etats-General were reconstituted as the National Assembly and then the National Constituent Assembly. he took his place with the conservative element, seated on the right side of the assembly.
He, along with many of the French clergy, opposed the revolutionary Civil Constitution of the Clergy that formalized the nationalization of church property and dissolved the remaining monastic establishments.
