Meaning & Origin
A male given name from the Germanic languages, variant of Alfonso.
Alonso is a boy's baby name of Germanic origin, a Spanish variant of Alfonso, from the Visigothic name Adelfonsus — combining elements meaning 'noble' and 'ready for battle.' Alonso has been a royal name in Spain for over a thousand years, borne by multiple Castilian and Aragonese kings.
Alonso has a warm, rounded sound that sits naturally in Spanish-speaking communities. It is most familiar to many through Don Alonso Quixano — the real name of the Man of La Mancha, Don Quixote, the most celebrated character in Spanish literature. With over 11,000 U.S. births, it carries deep Spanish cultural heritage.
