Louis Baraguey d'Hilliers (13 August 1764 – 6 January 1813) was a French Army general who fought in the French Revolutionary Wars and the Napoleonic Wars. He was the father of Achille Baraguey d'Hilliers, a Marshal of France, and the father-in-law of General Damrémont, governor-general of Algeria.
Louis Baraguay d'Hilliers was born in Paris. He was a minor noble and entered the French Army as a lieutenant in 1784. At the start of the French Revolutionary Wars, he decided to remain in France. By 1793, he had been promoted during the siege of Mainz to général de brigade and served as chief of staff to Adam Custine. When Custine was arrested, Baraguey d'Hilliers was arrested as well. Luckier than his chief who died under the guillotine, he was released after the overthrow and execution of Maximilien Robespierre.
In 1796, Baraguey d'Hilliers commanded part of Paris against insurgents. After another spell in prison on suspicion of royalist tendencies, he was posted to Louis Hoche's army. Transferred to Italy, he served under Napoléon Bonaparte as governor of Lombardy. He was involved in the capture of Bergamo. He led a brigade in Gabriel Rey's division at the Battle of Rivoli. Promoted to général de division in 1797 he was appointed governor of Venice.
