The Battle of Myriokephalon (also known as the Battle of Myriocephalum, Greek: Μάχη του Μυριοκέφαλου, Turkish: Miryokefalon Savaşı or Düzbel Muharebesi) was a battle between the Byzantine Empire and the Seljuk Turks in Phrygia in the vicinity of Lake Beyşehir in southwestern Turkey on 17 September 1176. The battle was a strategic reverse for the Byzantine forces, who were ambushed when moving through a mountain pass.

It was to be the final, unsuccessful effort by the Byzantines to recover the interior of Anatolia from the Seljuk Turks.
