Meaning & Origin
Maximilliano is a boy's baby name, an elaborate Spanish and Italian variant of Maximilian, from the Latin Maximilianus — itself a blend of Maximus (greatest) and Aemilianus — meaning 'the greatest Aemilian' or simply 'the greatest.'
Emperor Maximilian I of the Holy Roman Empire bore a version of this name in the 15th century, and Emperor Maximilian of Mexico in the 19th. The long, rolling form Maximilliano is favored in Latin American families who love names of full, resonant grandeur — a name that demands to be heard completely.
