Matos or Mattos, sometimes de Matos or de Mattos, is a Sephardic and Portuguese language surname.
The origin of the surname Matos or Mattos is toponymic. It was taken from a place with this designation, in the region of Lamego in Portugal. It originates in Egas Hermigues, great-grandson of King Ramiro II, from the Kingdom of León. Egas was of great valour and had the nickname of the "Bravo." He founded the convent of Freixo and made Mattos Farmhouse. His son and heir Hermigio Pais de Mattos followed the lineage. There are documents of Paio Hermigues de Mattos, contemporary of Kings Sancho II and Alfonso III of Portugal. Hermigio de Mattos was the owner of that farm and had others for honor. It is also a surname used by many Sephardic Jewish and converso families. "Matos" is a word in Hebrew that means "tribes", or in the more literal form, "wooden sticks". Francisca Nuñez de Carabajal, a Crypto-Jewish burned at stake in Mexico City by the Holy Office was condemned along her Crypto-Jewish husband, Francisco Rodríguez de Matos.
