The Battle of Vilcapugio (Quechua: Sacred Well) was an action fought on October 1, 1813 during the second Campaign of Upper Peru in the Argentine War of Independence, where the republican forces led by General Manuel Belgrano were defeated by a royalist army, led by Joaquin de la Pezuela.

After the Army of the North's victories during the Battles of Tucumán and Salta, the campaign against the royalists in Upper Peru was restarted upon the insistence of the government in Buenos Aires. Despite being ill with malaria and having to command a company of new conscripts with insufficient artillery, Belgrano accepted the commanding post.

Belgrano's army was supported from Oruro province by Colonel Baltasar Cárdenas and the 2,000 poorly organized natives under his command, and Colonel Cornelio Zelaya with forces from Cochabamba. Both colonels had orders to raise the aboriginal populations against the Spanish authorities. Knowing that the royalist army did not have enough mules to move its artillery and provisions, Belgrano planned to use a pincer movement to attack, confidently believing that Pezuela's lack of mobility would be a decisive factor.

At the end of September 1813, most of Belgrano's army arrived to the plain of Vilcapugio, a plateau surrounded by high mountains several miles north of Potosí. The royalist troops were encamped further west at Condo-Condo under the orders of Pazuela and Major Saturnino Castro, which allowed them to take by surprise and utterly defeat Cárdenas' native troops at Ancacato, 23 km north of Belgrano's headquarters. Castro also obtained documents from Cárdenas giving instructions to Belgrano. With these documents Pezuela was able to interrupt Belgrano's plans and began his advance on the mountains on 1 October, long before Zelaya's cavalry from Cochabamba could join the republican army at Vilcapugio. Belgrano's army veterans from the North contained the left flank and center column of the royalist army and forced them to back down to the point that Pezuela had in mind, by a moment, to send a message to the Viceroy of Peru intimating that the battle had been lost. His own left flank, however, remained in action and defeated Belgrano's right column. Had the Northern army continued to persist in pursuing the Spanish troops, victory would have been secured, but the arrival of the royalist cavalry commanded by Saturnino Castro made the rebels panic, causing them to disperse. The royalist army reorganized itself and appropriated all of its artillery, continuously shelling the few soldiers left in Belgrano's encampment. As result of the battle, 350 rebels and some 200 royalists were killed.
