Biridašwa (Sanskrit: "Prītāśva," "whose horse is dear" (Mayrhofer II 182)) was a mayor of Aštartu, (Tell-Ashtara), south of Damascus, (named Dimasqu/Dimašqu), during the time of the Amarna letters correspondence, about 1350–1335 BC.
A second mayor of Aštartu, Ayyab, existed in this short 15–20 year time period.
Though Biridašwa did not communicate with the Egyptian pharaoh directly in any of the Amarna letters, he, along with the mayors of Busruna and Halunnu were involved with the intrigues of city/city-state takeovers, in the region of Damascus.
The region around Dimašqu was named Upu, or Apu, a name going back to at least pharaoh Thutmose III's time, (1479-1425 BC).
The ending is mostly complete and has the referencing to Biridašwa.
