Étienne Clavier (26 December 1762 in Lyon – 18 November 1817 in Paris) was a French Hellenist and magistrate.
The son of a wealthy merchant of Lyon, he made early studies of the Classical languages, followed by studies of law in Paris. In 1788 he purchased a commission as conseiller au Châtelet of which he was soon deprived during the French Revolution. He entered the magistracy under the Directoire, serving as a judge in the criminal tribunal of the Seine, where he made himself prominent by the independence of his character in the trial of General Moreau. Pressured by Joachim Murat, who urged him to pronounce the capital sentence, with the assurance that Napoleon would grant clemency, he made the famous reply, "Et à nous, qui nous la fera?" He was finally discharged from his post in the reorganization of the tribunals of 1811.
