Andronikos Doukas, Latinized as Andronicus Ducas, (Greek: Ανδρόνικος Δούκας; died 14 October 1077) was a protovestiarios and protoproedros of the Byzantine Empire.
In 1071 Andronikos was the commander of a section of the Byzantine army in the campaign of Romanos IV Diogenes against the Seljuk Turks of Alp Arslan.
He was widely blamed for causing the crushing defeat of the Byzantine forces and the subsequent capture of Romanos IV by the enemy.
In 1072, after Romanos had been released by Alp Arslan, Andronikos and his brother Constantine were sent out by Michael VII and their father the Caesar John to intercept him.
Both were captured by the rebels, who released the badly wounded Andronikos to allow him to seek proper medical treatment in Constantinople.
