Diego is a Spanish boy's name of uncertain origin. It is often explained as a form of Santiago, Spanish for Saint James, though its Latin form, Didacus, has also been linked to a Greek word for teaching. In Spanish it is pronounced dee-AY-go, and English speakers say it much the same way.
Two celebrated artists bore the name: Diego Velázquez, court painter to King Philip IV of Spain, and Diego Rivera, whose frescoes helped establish the Mexican mural movement. The California city of San Diego is named after Saint Diego of Alcalá, a 15th-century Spanish friar.
In the United States, Diego climbed from 628th in 1980 to its peak of 56th in 2006. It has slipped since then and ranked 158th in 2025, when 2,351 babies were given the name.
