Kashta (flourished c. 750 bce) was a Kushite king who Egyptianized Nubia and conquered Upper Egypt. He was the brother and successor of Alara and the father of Piye (Piankhi), who conquered the rest of Egypt, and of Shabaka, who succeeded Piye and founded the 25th (Kushite) dynasty of ancient Egypt (see ancient Egypt: The 24th and 25th dynasties).
