Duarte
A Portuguese and Spanish surname ultimately tied to the old name Edward, meaning “wealthy guardian” or “prosperous protector.”
The #808 most common surname in the United States (2010 Census) — about 1 in every 7,183 Americans shares it.
Etymology
Duarte is the Portuguese form of the personal name Edward, which entered Romance naming through older Germanic tradition. The old name is usually explained as meaning something like “rich guardian” or “prosperous protector,” from Germanic elements for wealth and guard. As a surname, Duarte would originally have identified someone as a descendant of, or person connected with, a man named Duarte/Edward.
History
The name is especially associated with Portuguese and Spanish-speaking communities, where it spread as both a given name and a hereditary surname. Older surname collections also note related forms such as Duart, Eduardo, and other regional spellings. Because the personal name was widely used in Iberia, the surname developed independently in multiple families rather than from one single ancestor.
