Acmonia or Akmonia (Ἀκμονία) is an ancient city and a titular see of Phrygia Pacatiana, in Asia Minor, now known as Ahat Köyü. It is mentioned by Cicero (Pro Flacco, 15) and was a point on the road between Dorylaeum and Philadelphia.
In 2000, a large mosaic floor depicting a gymnasium was discovered in Acmonia. Despite the emergency excavations, which started on 26 June 2000, one part of the mosaic was stolen from the excavation site. The stolen parts were later recovered in Istanbul after a police raid in 2002.
