Fasilides, also known as Fasil, Basilide, or Basilides, was Emperor of Ethiopia from 1632 to his death on 18 October 1667, and a member of the Solomonic dynasty. His throne name was Alam Sagad.

The emperor of Ethiopia, also known as the Atse, was the hereditary ruler of the Ethiopian Empire, from at least the 13th century until the abolition of the monarchy in 1975. The emperor was the head of state and head of government, with ultimate executive, judicial and legislative power in that country. A National Geographic article from 1965 called imperial Ethiopia "nominally a constitutional monarchy; in fact [it was] a benevolent autocracy".
