Gonzalo is a Spanish name that comes from the medieval Gundisalvus, a Latinized Visigothic name whose first element gund means "battle"; the second part is uncertain. It was borne by the 11th-century Castilian hero Gonzalo Fernández and remains a classic in Spain and Latin America. In the United States Gonzalo ranked number 695 in 2000 and has gradually fallen out of the top 1000, standing at number 1423 in 2025.
