Teodoro Trivulzio (1458–1531) was an Italian condottiero and marshal of France.
He was born in Milan, the nephew of Gian Giacomo Trivulzio.
He assisted Marshal Odet de Foix in the siege of Parma in 1521, and was named governor of Milan in 1525.
Trivulzio had however to leave the latter position after the battle of Pavia in the same year, which marked the French collapse in northern Italy.
In 1526 he was created marshal of France by King Francis I, receiving the position of Governor of Genoa.
