Paropamisadae or Parapamisadae (Greek: Παροπαμισάδαι) was a satrapy of the Alexandrian Empire in modern Afghanistan and Pakistan, which largely coincided with the Achaemenid province of Parupraesanna. It consisted of the districts of Sattagydia (Bannu basin), Gandhara (Kabul, Peshawar, and Taxila), and Oddiyana (Swat Valley). Paruparaesanna is mentioned in the Akkadian language and Elamite language versions of the Behistun Inscription of Darius the Great, whereas in the Old Persian version it is called Gandāra. The entire satrapy was subsequently ceded by Seleucus I Nicator to Chandragupta Maurya following a treaty.
