Bernabé Aráoz (1776 – 24 March 1824) was a governor of Tucumán Province in what is now Argentina during the early nineteenth century, and President of the short-lived Republic of Tucumán. Aráoz came from a wealthy and influential family in the northern province of Tucumán in the Spanish Viceroyalty of the Río de la Plata, and was a leader of the local militia. In 1810 he supported the May Revolution in which the leaders in Buenos Aires declared independence from the Napoleonic regime in Spain. He played a decisive role in the crucial Battle of Tucumán fought in 1812 against the royalists, and was made governor of his province.
