Heráldica Hispana is an online reference portal dedicated to Spanish, Hispanic American, and Spanish-Filipino heraldry. Its collection features 18,773 coats of arms, with images created by the site and protected by copyright since 1995. Visitors can explore arms with mantling, browse heraldic entries, and consult resources on basic heraldic terminology, legislation, shield quarters, and composition. Frequently asked questions and a contact option provide additional guidance.

The site includes a search function designed to accommodate uppercase and lowercase letters, accents, umlauts, and the letter ñ. It also recommends searching with the first letters of a surname when its exact spelling is uncertain. Visitors with reliable documentation about an unlisted coat of arms, or information about an error in a published entry, are invited to contact the site.

Heráldica Hispana traces its origins to an earlier website launched in 1995 and now operates several independent domains with separate databases. Images may be used for personal purposes only; commercial use requires express written permission.
