The Battle of Maida, fought on 4 July 1806 was a battle between the British expeditionary force and a French force outside the town of Maida in Calabria, Italy during the Napoleonic Wars. John Stuart led 5,236 Anglo-Sicilian troops to victory over about 5,400 Franco-Italian-Polish troops under the command of French general Jean Reynier, inflicting significant losses while incurring relatively few casualties. Maida is located in the toe of Italy, about 30 kilometres (19 mi) west of Catanzaro.

Jean Louis Ebénézer Reynier was a Swiss-French military officer who served in the French Army under the First Republic and the First Empire. He rose in rank to become a general during the French Revolutionary Wars and led a division under Napoleon Bonaparte in the French campaign in Egypt and Syria. During the Napoleonic Wars, he continued to hold important combat commands, eventually leading an army corps during the Peninsular War in 1810–1811 and during the War of the Sixth Coalition in 1812–1813.
