Garmekan or Garamig was an early Sasanian province located in northern Mesopotamia, between the Little Zab and Diyala river. Its capital was Karka d-Beth Slokh. The province is omitted in Shapur I's (r. 240–270) list of provinces in the Ka'ba-ye Zartosht inscription, which indicates that it was part of Nodshiragan during that period. Garmekan is first attested as a Sasanian province in the Paikuli inscription of Narseh (r. 271–293) in 293/4, who describes how the aristocracy of Asoristan, Garmekan, and Shahrazur met him at Hayan i Nikatra in order to convince him to become the new king. Before the Council of Seleucia-Ctesiphon in 410, Garmekan had been merged with the province of Nodshiragan, becoming known as Garamig ud Nodardashiragan.
