Joseph Tarchaneiotes (Greek: Ιωσήφ Ταρχανειώτης) was a Byzantine general primarily known for his lack of participation in the decisive Battle of Manzikert (1071).
An experienced general, Joseph was second-in-command of the Byzantine operation at Manzikert, with some 30,000–40,000 soldiers under his command.
[1] Tarchaneiotes's segment of the army was detached to take nearby Khliat before the main battle took place.
Tarchaneiotes's lack of participation in the campaign, whether due to treachery, dissatisfaction, or a defeat in battle, seriously undermined Romanos IV's (r. 1068 – 1071) ability to fight at Manzikert.
Joseph died in 1074, whilst serving as the doux of Antioch, and was succeeded by his son Katakalon Tarchaneiotes.
