Konstantinos Photiadis (Greek: Κωνσταντίνος Φωτιάδης; died 1897) was the Ottoman-appointed Prince of Samos from 1874 to 1879. Johann Strauss, author of "A Constitution for a Multilingual Empire: Translations of the Kanun-ı Esasi and Other Official Texts into Minority Languages," stated that he held the highest positions a Christian could in the empire and described him as one of several "Eminent figures of the Greek community", in which he participated. He held a teaching position at the "Great National School" (Megalē tou Genous scholē), with the literature in the Turkish language being his subject of instruction.
