Addaya was an Egyptian commissioner during the period of the Amarna letters correspondence (1350–1335 BC).
The majority of the Amarna letters were written to the pharaoh of Egypt during a 15-20 year(?)
3 of 3 by Labaya, the person who was aligned with the Habiru of Canaan, the Habiru being one of the main topics of the entire body of Amarna letters.
Addaya is also in three letters by Abdi-Heba of Jerusalem, (called Uru-salim in the Amarna letters – EA 289, URU-Ú-ru-sa-lim, "(City)-Uru-salim").
Because Addaya is only mentioned in the letters of Uru-salim, and Šakmu-(of Labaya, modern Shechem-(Nablus)), it can be assumed that Addaya only did business in southern Canaan, or at least in the area of Jerusalem.
