Louis Bourdaloue was a French Jesuit and preacher.
He was born in Bourges. At the age of sixteen he entered the Society of Jesus, and was appointed successively professor of rhetoric, philosophy and moral theology, in various Jesuit colleges. His success as a preacher in the provinces led his superiors to call him to Paris in 1669 to occupy for a year the pulpit of the church of St. Louis. Owing to his eloquence he was speedily ranked in popular estimation with Corneille, Racine, and the other leading figures of the height Louis XIV's reign. He preached at the court of Versailles during the Advent of 1670 and the Lent of 1672, and was subsequently called again to deliver the Lenten course of sermons in 1674, 1675, 1680 and 1682, and the Advent sermons of 1684, 1689 and 1693. This was all the more noteworthy as it was the custom never to call the same preacher more than three times to court.
On the Revocation of the Edict of Nantes he was sent to Languedoc to confirm the new converts in the Catholic faith, and he had much success in this delicate mission. Catholics and Protestants were unanimous in praising his fiery eloquence in the Lent sermons which he preached at Montpellier in 1686. Towards the close of his life he confined his ministry to charitable institutions, hospitals and prisons. He died in Paris on 13 May 1704.
