Petros Lantzas (Greek: Πέτρος Λάντζας; Italian: Pietro Lanza or Spanish: Pedro Lanza) c. 1533 - 26 February 1613), was a Corfiot Greek, spy, privateer and pirate in the 16th century Balkans who took part in several anti-Ottoman plots. He initially worked for the Republic of Venice and from 1574 was employed by the Spanish Empire. Lantzas was involved in various plots to overthrow Ottoman rule in Greek-inhabited regions. In 1608, he devised a plan to assassinate the Ottoman sultan Murad III by placing a present containing explosives in front of him.
