Tovar, usually preceded by the particle de (meaning from), is a surname that was adopted in the Middle-Ages by a Castilian noble house that received the lordship of the village of Tovar from Fernando III.
It has since spread to several Spanish and a few Portuguese branches.
The Tovar surname in the Americas appears mainly as a toponymic derived from the many settlements of this name founded there by the Spanish, and therefore does not share the same genealogical origin.
