The Battle of Calderón Bridge () was a decisive battle in the Mexican War of Independence, fought on the banks of the Calderón River east of Guadalajara in present day Zapotlanejo, Jalisco. Almost 100,000 Mexican revolutionists contributed to the attack, commanded by Miguel Hidalgo, Ignacio Allende, Juan Aldama and Mariano Abasolo. The Royalist forces, made up of little more than 6,000 professional soldiers, and fighting for the King of Spain, were led by Félix María Calleja del Rey, a Spanish military officer and (later) viceroy of New Spain. He was later given the title of conde de Calderón for the victory.
