Alexios Kaballarios or Kaballares (Ancient Greek: Ἀλέξιος Καβαλλάριος/Καβαλλάρης) was a Byzantine aristocrat and military commander, cousin of Emperor Michael VIII Palaiologos (r. 1259–1282).
[1] He participated in the Byzantine campaigns in the Morea in the early 1260s, and was taken prisoner by William II of Villehardouin after the Battle of Makryplagi (1263/64).
[2] Apparently released at some later date, in c. 1270, he held the offices of domestikos tes trapezes and governor in Thessaly or Thessalonica.
[1][3] Along with his cousin, the despotes John Palaiologos, he led a Byzantine army against John I Doukas of Thessaly, but was defeated and killed in the Battle of Neopatras in c. 1273/74.
