The Tabnit sarcophagus is the sarcophagus of the Phoenician King of Sidon Tabnit, the father of King Eshmunazar II. It is decorated with two separate and unrelated inscriptions – one in Egyptian hieroglyphs and one in the Phoenician alphabet. The latter contains a curse for those who open the tomb, promising impotency and loss of an afterlife.

Eshmunazar II was the Phoenician king of Sidon. He was the grandson of Eshmunazar I, and a vassal king of the Persian Achaemenid Empire. Eshmunazar II succeeded his father Tabnit I who ruled for a short time and died before the birth of his son. Tabnit I was succeeded by his sister-wife Amoashtart who ruled alone until Eshmunazar II's birth, and then acted as his regent until the time he would have reached majority. Eshmunazar II died prematurely at the age of 14. He was succeeded by his cousin Bodashtart.
