Oswaldo is Germanic, Old English, Portuguese, Spanish in Origin.

Oswaldo is the Spanish and Portuguese form of Oswald, a Germanic name best attested in Old English as Ōsweald. Its first element, ōs, belongs to the Anglo-Saxon word for a god or divinity, cognate with Old Norse áss; the second, weald, is related to wealdan, to rule or wield authority. The literal sense is therefore divine rule or godly power.

The name’s historical profile was shaped by Saint Oswald, the seventh-century king of Northumbria killed at Maserfield in 642, whose cult carried the name into medieval Christian use. Oswaldo reflects later Iberian adaptation, with final -o matching Spanish and Portuguese masculine patterns; Osvaldo, Oswald, Osvald, and Ósvaldur are cognate forms. In Latin America it appears in public life through figures such as Brazilian physician Oswaldo Cruz and Ecuadorian painter Oswaldo Guayasamín. U.S. records peak in the 2000s, then decline.
