Pedro Navarro, Count of Oliveto (c. 1460 – 28 August 1528) was a Navarrese military engineer and general who participated in the War of the League of Cambrai. At the Battle of Ravenna in 1512 he commanded the Spanish and Papal infantry, but was captured by the French. In the service of Francis I of France, he would supervise the French crossing of the Alps before the Battle of Novara in 1513. He is widely regarded as the inventor of modern land mines.
