The Battle of Raab or Battle of Győr was fought on 14 June 1809 during the Napoleonic Wars, between Franco-Italian forces and Habsburg forces. The battle was fought near Győr, Kingdom of Hungary, and ended in a Franco-Italian victory. The victory prevented Archduke John of Austria from bringing any significant force to the Battle of Wagram, while Prince Eugène de Beauharnais's force was able to link up with Emperor Napoleon at Vienna in time to fight at Wagram. Napoleon referred to the battle as "a granddaughter of Marengo and Friedland", as it fell on the anniversary of those two battles.

Archduke John of Austria, a member of the House of Habsburg-Lorraine, was an Austrian field marshal and imperial regent (Reichsverweser) of the short-lived German Empire during the Revolutions of 1848.
