Etymology
Acuña is generally treated as a Spanish locational surname, ultimately tied to place-names in Spain. The name is often connected with the Basque word or place-element related to a hill or mound, though the exact derivation can vary by locality. In practice, it likely began as an identifier for someone from a place called Acuña or something similar.
History
The surname is found in Spain and later across the Spanish-speaking world, especially through migration to the Americas. In modern usage it is often written without the tilde as Acuna in countries and records that do not use ñ. A well-known bearer is Venezuelan baseball star Ronald Acuña Jr., which has helped make the name familiar internationally.
