Meaning and origin of Diego

Diego is often said to mean “uncertain; possibly a form of James”; the origin is uncertain, though it is usually linked to Spanish roots.

Diego is a Spanish name whose origin is debated. One common explanation is that it arose from Santiago, Saint James, when Sant Yago was misheard as San Diego. Another links it to the medieval Latin Didacus, sometimes connected with a Greek word for teaching. Neither account is certain, so it is best described as uncertain. The name has been used in Spain for many centuries and is borne by the painter Diego Velazquez and the muralist Diego Rivera. It is warm, rhythmic and widely known across the Americas, and the city of San Diego keeps it familiar in the United States.
