Meaning & origin
Alanzo is a rare, revived spelling variant that first appeared on U.S. birth records in 1882, the peak year for its use at that time. After decades of near-dormancy, it began a steady climb in popularity starting in 1986, a trajectory that continues into the 2020s. In 2025, the name was given to roughly 1 in every 106,755 newborn boys, placing it at rank 5,608. Its revival reflects a broader interest in vintage and romantic-sounding Hispanic names. While Alanzo has never charted in any state's top names, its gradual upward trend suggests it remains an uncommon but recognizable choice.
Alanzo is a variant spelling of Alonzo, itself an Italian form of Alfonso. Alfonso derives from the Visigothic name Adalfuns, composed of elements meaning 'noble' and 'ready' or 'eager'. The name spread through the Iberian Peninsula and was borne by numerous kings of Spain and Portugal. The Alanzo spelling emerged in the United States in the late 19th century, likely as a phonetic or creative variant.
