Dalma culture was a prehistoric archaeological culture of north-western Iran dating to early fifth millennium B.C. Later, it spread into the central Zagros region and elsewhere in adjacent areas. Its widespread ceramic remains were excavated in central and northern valleys of the Zagros Mountains in north-western Iran. Dalma assemblages were initially discovered by the excavations carried out at Dalma Tepe and Hasanlu Tepe in south-western parts of Lake Urmia, in the valley of Solduz.

Teppe Hasanlu or Hasanlu Tepe is an archeological site of an ancient city located in northwest Iran, a short distance south of Lake Urmia. The nature of its destruction at the end of the 9th century BC essentially froze one layer of the city in time, providing researchers with extremely well preserved buildings, artifacts, and skeletal remains from the victims and enemy combatants of the attack. The site was likely associated with the Mannaeans.
