Aesop Rock (born Ian Matthias Bavitz on June 5, 1976) is an American hip hop artist and producer.

He is signed to El-P's Definitive Jux label and is a current member of The Weathermen. Regarding his name, he said: "I acquired the name Aesop from a movie I had acted in with some friends. It was my character's name and it sort of stuck. The rock part came later just from throwing it in rhymes."
