The Battle of Andrassos or Adrassos was an engagement fought on 8 November 960 in an unidentified mountain pass on the Taurus Mountains, between the Byzantines, led by Leo Phokas the Younger, and the forces of the Hamdanid Emirate of Aleppo under the emir Sayf al-Dawla.

In mid-960, taking advantage of the absence of much of the Byzantine army on campaign against the Emirate of Crete, the Hamdanid prince launched another invasion of Asia Minor, and raided deeply and widely into the region of Cappadocia. On his return, however, his army was ambushed by Leo Phokas at the pass of Andrassos. Sayf al-Dawla himself barely escaped, but his army was annihilated.

Both contemporary Arab and modern historians, such as Marius Canard and J. B. Bikhazi, have commonly considered the defeat at Andrassos as a decisive engagement that destroyed Hamdanid offensive abilities for good, and opened the path for Nikephoros Phokas' subsequent exploits.
