Julián Romero de Ibarrola (Huélamo, 1518 – Cremona, 1577) was a Spanish military commander in the 16th century. He was one of the few common soldiers in the Spanish army to reach the rank of Maestre de Campo. In 1565 he was stationed in Sicily, but the following year, the Duke of Alba made him Maestre de campo, and he accompanied the Duke to the Low Countries to crush the Dutch Revolt. In 1568 he commanded the guard at the execution of Counts Egmont and Horn.
