Leo Tuscus (or Leo the Tuscan, fl. 1160/66–1182/83) was an Italian writer and translator who served as a Latin–Greek interpreter in the imperial chancery of the Byzantine Empire under Emperor Manuel Komnenos. Leo was born in the first half of the twelfth century in Pisa. He was the younger brother of Hugo Etherianus. Nothing about his early life or education is known, nor where he and his brother acquired Greek.
