André Masséna (in Italian Andrea Massena) 1st Duc de Rivoli, 1st Prince d'Essling (May 6, 1758 – April 4, 1817) was a French military commander during the Revolutionary and Napoleonic Wars.

Masséna was one of the original eighteen Marshals of the Empire created by Napoleon. His nickname was l'Enfant chéri de la Victoire ("the Dear Child of Victory").

Napoleon said of Masséna: he was "the greatest name of my military Empire." According to Donald D. Horward, "Masséna's military career was equaled by few commanders in European history. In addition to his remarkable battlefield successes, he touched the careers of many who served under his command."

André Masséna was born in Nice, then part of the Kingdom of Sardinia, the son of a shopkeeper Jules Masséna (Giulio Massena) and wife Marguerite Fabre, married on August 1, 1754. His father died in 1764, and after his mother remarried he was sent to live with relatives.

At the age of thirteen, Masséna became a cabin boy aboard a merchant ship; he sailed with it around the Mediterranean and on two extended voyages to French Guiana. In 1775, after four years at sea, he returned to Nice and enlisted in the French Army as a private in the Royal Italian regiment. He had risen to the rank of warrant officer (the top rank for a non-nobleman) when he left in 1789. In the same year he married on August 10 Anne Marie Rosalie Lamare (Antibes, September 4, 1765 – Paris on January 3, 1829) and they remained living at her birthplace. After a brief stint as a smuggler in Northern Italy (his knowledge of the road networks would later prove useful), he rejoined the army in 1791 and was made an officer, rising to the rank of colonel by 1792.
