Konstantinos Doumpiotis (Greek: Κωνσταντίνος Δουμπιώτης) was a Greek revolutionary and military officer. He was born around 1793 in Doubia of Chalkidiki, the son of Theofilos Doumpiotis. He served the Ottoman administration of Chalkidiki as a subaşi in the Mademochoria. Along with his siblings Vasilikos, Stergios, Nikolaos, Polychronis, and the Kassandrine Anastasios Chymeftos, he participated in the Greek War of Independence in Chalkidiki as one of the lieutenants of Emmanouel Pappas. After the suppression of the Greek uprising in Chalkidiki in November 1821 he went to Naoussa, where he fought alongside Anastasios Karatasos. After the destruction of Naoussa he fled to Skopelos through Aspropotamos and Zagora.
