Palà was an ancient region of Anatolia to the northwest of Hattusa at the time the Hittites took control of the land of Hatti. Its inhabitants spoke an Indo-European language called palaumnili and appear to have coexisted with the Hattians for centuries prior. They are lost to history with the advance of Kaskian peoples from the east in the early 1500s BC.
