Francis-Xavier de Montmorency-Laval, commonly referred to as François de Laval (30 April 1623 – 6 May 1708), was a French prelate of the Catholic Church. Consecrated a bishop in 1658, he led the Apostolic Vicariate of New France from 1658 to 1674 and then became the first bishop of the Diocese of Quebec from its erection in 1674 until he retired because of poor health in 1688. He continued to work in New France until his death in 1708. Among his accomplishments was the founding of the Séminaire de Québec in 1663. Laval was a member of the Montmorency family, but renounced his rights as heir so he could pursue his ecclesiastical career.
