The surname Andrade is found predominantly in Portugal and Spain, and in countries of Latin America, Italy, Equatorial Guinea and East Timor, Goa, and Karnataka in India. There is an important concentration of Andrade families residing in the United States, specifically, California, Massachusetts, Hawaii and Rhode Island.

The Andrade, sometimes spelled Andrada, became a powerful family in north-western Iberia during the late Middle Ages and the early Renaissance, time during which they held the titles of Counts of Andrade and Vilalba, amongst others, together with numerous castles, palaces, manor houses and extensive lands.

The two Galician Regions of Ferrolterra and Terra Chá are known to have been part of the domains of Fernán Pérez de Andrade in the 14th century. Most of the Galician properties, palaces and castles of the Andrade family these days belong to the House of Alba, and the present Countess of Andrade is Cayetana Fitz-James Stuart, 18th Duchess of Alba.
