Léon Ménard (12 September 1706 – 1 October 1767) was a French lawyer and historian.
He was a member of the Académie des Inscriptions et Belles-Lettres, and several other learned bodies.
His first work concerned the history of his native city and its bishops, and was entitled "Histoire des évêques de Nîmes" (2 vols., The Hague, 1737).
Later he enlarged this work, and between 1760 and 1758 he published at Paris the "Histoire civile, ecclésiastique et littéraire de la ville de Nîmes" in seven volumes with illustrations.
In 1762 the Magistracy of Avignon sent for him and confided to him the task of writing a history of that city.
