Maroboduus, also known as Marbod, was a king of the Marcomanni, who were a Germanic Suebian people. He spent part of his youth in Rome, and returning, found his people under pressure from invasions by the Roman empire between the Rhine and Elbe. He led them into the forests of Bohemia, near to the Quadi who already lived nearby, and established a large alliance.

The Marcomanni were a Germanic people that established a powerful kingdom north of the Danube, somewhere near modern Bohemia, during the peak of power of the nearby Roman Empire. According to Tacitus and Strabo, they were Suebian.
