Afonso I das Astúrias (? — 757) foi Rei das Astúrias e Duque da Cantábria desde 739, descendente do rei visigodo Recaredo. Alguns autores indicam que terá casado com Ermesinda, filha de Pelágio, tornando-se, portanto, seu genro e herdeiro do trono. Era herdeiro das terras na Cantábria por parte do seu pai, o Duque Pedro de Cantábria.
Afonso I autoproclama-se Rei das Astúrias, ao contrário de Pelágio e seu filho Fávila, e, com ele, retoma-se a Reconquista, aproveitando as guerras internas dos mouros. Anexa-se a Galiza em 740, Leão em 754. Governou durante 19 anos.
He was born in Cantabria in 693. 
He was the son of Peter of Cantabria
As the son of Duke Peter of Cantabria, Alfonso held many lands in that region. 
He was King of Asturias from 739-757, preceding Favila and followed by Fruela I. He was a ruler of the Astur-Leonese dynasty.
Alfonso I of Asturias, called the Catholic (el Católico), (c. 693 – 757) was the third King of Asturias, reigning from 739 to his death in 757. His reign saw an extension of the Christian domain of Asturias, reconquering Galicia and León.
He succeeded his brother-in-law Favila, and was succeeded by his son, Fruela I. Alfonso's youngest son, Mauregatus, also became king, and his daughter Adosinda was consort to king Silo of Asturias. The dynasty started by Alfonso was known in contemporary Al-Andalus as the Astur-Leonese dynasty.
He married Ermesinda.
He is said to have married Ermesinda, daughter of Pelagius, who founded Asturias after the Battle of Covadonga in which he reversed the Moorish conquest of the region. He succeeded Pelagius' son, his brother-in-law, Favila, on the throne after the latter's premature death.
Whether Pelagius or Favila were ever considered kings in their own lifetime is debatable, but Alfonso certainly was. 
He began a lifelong war against the Moors. In 740, he conquered Galicia and in 754, León. He went as far as La Rioja. However, the few urban populations of these frontier regions fled to his northern dominions, leaving a depopulated buffer between the Christian and Muslim states.
This created the so-called Desert of the Duero, an empty region between the River Duero and the Asturian Mountains. Alfonso intended it this way; he wished to leave such a zone where any invading army would find it too difficult to survive. Besides the martial, the demographic and cultural effects of this policy on later Asturian, Spanish and Portuguese history is large. It was over a hundred years before the region was repopulated (an event known as the Repoblación).
The Arab writers speak of the kings of the northwest of Iberia as the Beni Alfons (descendants or House of Alfonso), and appear to recognize them as a Galician royal stock derived from Alfonso I. 
Alfonso is credited with establishing the shrine of Our Lady of Covadonga, in commemoration of his father in law's victory at the Battle of Covadonga. He and his queen are interred there. Their epitaph reads:
QVI YAZE EL CATOLICO Y SANTO REI DON ALONSO EL PRIMERO I SV MVJER DOÑA ERMENISINDA ERMANA DE DON FAVILA A QVIEN SVCEDIO. GANO ESTE REY MVCHAS VITORIAS À LOS MOROS. FALLECIO EN CANGAS AÑO DE 757." "Here lies the Catholic and Holy King Don Alfonso the First and his wife Doña Ermesinda, sister of Don Favila to whom he succeeded. This king won many victories against the Moors. He died in Cangas in the year 757
He died in 757 in Cangas de Onís, Asturias. He was buried at Santa Cueva de Covadonga.
Alfonso had four children. Three were through his marriage to Ermesinda, although Mauregatus was born to a Muslim slave, Sisalda.
