Meaning & origin
Oswaldo, a variant of Oswald, has a meaning rooted in Old English: 'God's power.' While the name first appeared in U.S. records in 1915, its peak usage came nearly a century later in 2006, when it reached its highest rank. Since then, it has been falling in popularity, a trajectory that continues into 2025, where it ranks 2991 with a 1-in-41660 incidence rate. The name is especially favored in Texas and California, reflecting its strong ties to Spanish-speaking communities. Despite its decline, Oswaldo remains a distinctive choice with a powerful etymology.
Oswaldo is a variant of Oswald, derived from the Old English elements 'os' (god) and 'weald' (power, rule). It was introduced to the Iberian Peninsula and Italy through Germanic influence and has long been used in Spanish- and Portuguese-speaking communities, where it took on the -o ending typical of those languages. The name remains moderately common in Latin America.
