Constantine Doukas Nestongos

{{Short description|13th-century Byzantine aristocrat}}

Constantine Doukas Nestongos ({{langx|el|Κωνσταντῖνος ∆ούκας Νεστόγγος}}, {{fl.|1280–1307}}) was a Byzantine aristocrat and courtier.

Nestongos first appears in 1280, when he accompanied the co-emperor (and future sole emperor) Andronikos II Palaiologos in his campaign against the Turks in the Maeander River valley. Nestongos at the time held the position of {{Lang|grc-latn|parakoimomenos}} of the imperial seal.{{sfn|PLP|loc=20201. Νεστόγγος, Κωνσταντῖνος ∆ούκας}} Appointed governor of Nyssa, he held the post until the city fell to the Turks in ca. 1284.{{sfn|PLP|loc=20201. Νεστόγγος, Κωνσταντῖνος ∆ούκας}} Nestongos himself was captured, but had been released by June 1285, when he witnessed a treaty with the Republic of Venice.{{sfn|PLP|loc=20201.

He is last mentioned in ca. 1307, in a legal dispute between some of his tenants ({{Lang|grc-latn|paroikoi}}) near Smyrna with a local monastery.{{sfn|PLP|loc=20201. Νεστόγγος, Κωνσταντῖνος ∆ούκας}} Some authors identify him with a "Doukas Nestongos" who was {{Lang|grc-latn|megas hetaireiarches}} in 1304, but this is unlikely since the latter post was much junior in rank to the {{Lang|grc-latn|parakoimomenos}}.{{sfn|PLP|loc=20201.
