The megas dioikētēs (Greek: μέγας διοικητής) was a Byzantine court dignity during the Palaiologan period.
The dioikētēs was a provincial fiscal administrative post, which however was replaced in the early 12th century by the praktōr.
[4] In other contemporary lists of offices his position varies, but is far lower, coming usually right after the logariastēs tēs aulēs.
[11] Pseudo-Kodinos also provides information on the dignity's court dress: a skiadion hat with gold-wire embroidery, a "plain silk" kaftan-like kabbadion, and a ceremonial domed hat called skaranikon, covered with velvet and topped with a red tassel.
[12] Only a handful of holders are known by name: the writer and official Theodore Kabasilas in 1316–1322;[13] the katholikos kritēs Glabas in 1330–1341;[14] and the sebastos John Doukas Balsamon, megas dioikētēs at Thessalonica in 1355, known only from an act concerning the Docheiariou monastery.
