Sattagydia (Old Persian: 𐎰𐎫𐎦𐎢𐏁 Thataguš, country of the "hundred cows") was one of the easternmost regions of the Achaemenid Empire, part of its Seventh tax district according to Herodotus,[5] along with Gandārae, Dadicae and Aparytae.

[6][7][8] It was situated east of the Sulaiman Mountains up to the Indus River in the basin around Bannu in modern day's southern Khyber Pakhtunkhwa, Pakistan.

[9] Magee et al. have reported findings of recent archaeological excavations at Akra, noting that it was a large urban site that existed throughout the Iron Age and had trade relations with Central Asia.

[12] Representatives of Sattagydia are depicted as delegates bringing gifts to the king on the Apadana staircases, and as throne/ dais bearers on the Tripylon and Hall of One Hundred Columns reliefs at Persepolis.

[16][need quotation to verify][17] And, beginning in the 1st century BC, the area was incorporated into the burgeoning Kushan Empire, referred to as "Scythia" in the Periplus.
