Dominguez

Dominguez, also spelled Domínguez, is a Spanish patronymic surname meaning "son of Domingo," from the given name Domingo, which itself derives from Latin Dominicus meaning "of the Lord." The suffix -ez indicates lineage. The name exists with several diacritics; in English contexts it is often written Dominguez.

The surname is common in Spain and across Latin America, where it spread with Spanish colonization and subsequent migration. In the United States it is particularly prevalent in California, Texas, Florida, and other areas with Hispanic communities, reflecting historical and modern immigration.

In addition to being a family name, Dominguez appears in various geographic and institutional names, most notably California State University, Dominguez Hills, located in Carson, California. The Dominguez Channel, a waterway in the Los Angeles metropolitan area, bears the name as well and traces back to early landowners in the region.

Notable individuals with the surname include Carlos Dominguez III, a Philippine economist and former Secretary of Finance, among others. The accent form Domínguez is standard in Spanish-language usage, and many non-Spanish contexts preserve the base spelling Dominguez.
