Tewoflos or Theophilus (Ge'ez ቴዎፍሎስ, throne name Walda Ambasa, Ge'ez ወልደ አምበሳ, "son of the lion") was Emperor of Ethiopia (1 July 1708 – 14 October 1711) and a member of the Solomonic dynasty. He was the brother of Iyasu I, and one of four sons of Fasilides.
Following the murder of his nephew Tekle Haymanot I, Tewoflos was brought out of captivity at Mount Wehni and made Emperor. His reign was an unquiet one. In 1709, Nebahne Yohannes was proclaimed Emperor in a revolt that lasted until July 1710.
Tewflos died under suspicious circumstances. He was buried at Teda.
