Ottavio Piccolomini (1599–1656), of the Sienese Piccolomini, enlisted as a Spanish pikeman and rose to imperial field marshal in the Thirty Years' War. He fought at the White Mountain in 1620 and captained Wallenstein's personal guard from 1627.

During the Mantuan War he was held hostage at Ferrara to 1631. At Lützen in 1632 five horses were shot under him, and he helped overthrow Wallenstein in 1634.
