The Congregation of the Oratory of Jesus and Mary Immaculate, best known as the French Oratory, is a society of apostolic life of Catholic priests founded in 1611 in Paris, France, by Pierre de Bérulle (1575–1629), later a cardinal of the Catholic Church. They are known as Bérullians or Oratorians. The French Oratory had a determinant influence on the French school of spirituality throughout the 17th century. It is separate and distinct from the Oratory of Saint Philip Neri, which served as its inspiration.

Pierre de Bérulle was a French Catholic priest, cardinal and statesman in 17th-century France. He was the founder of the French school of spirituality, who could count among his disciples Vincent de Paul and Francis de Sales (?), although both developed significantly different spiritual theologies.
