Armand-Jacques Leroy de Saint-Arnaud (20 August 1798 – 29 September 1854) was a French soldier and Marshal of France. He served as French Minister of War until the Crimean War when he became Commander-in-chief of the army of the East.
He was a key conspirator in the 1851 French coup d'état which dissolved the National Assembly, granted dictatorial powers to Napoleon III and caused the dissolution of the French Second Republic.
