Meaning and history
Emiliano is the Spanish, Italian, and Portuguese form of the Roman cognomen Aemilianus, which came from the family name Aemilius (see Emil). It was borne by a 6th-century Spanish saint, also known as Millán.
Emiliano has risen sharply in the modern US rankings, moving from #634 in 2000 to #94 in 2025. It now stands at #94 for boys. That year also produced its highest recorded birth count, at 3,701.
