Susenyos I (Ge'ez: ሱስንዮስ Sūsinyōs; c. 1571–1575 – 17 September 1632), also known as Susenyos the Catholic, was Emperor of Ethiopia from 1607 to 1632, and a member of the Solomonic dynasty. His throne names were Seltan Sagad and Malak Sagad III.
He was the son of Abeto Fasil, as well as the grandson of Abeto Yakob and the great-grandson of Dawit II. As a result, while some authorities list Susenyos as a member of the Solomonic dynasty, others consider him—rather than his son, Fasilides—as the founder of the Gondar line of the dynasty (which is, however, ultimately a subset of the Solomonic dynasty).
The life of Susenyos is known through his chronicle, written by several official writers (sehafe te’ezaz).
