Theodosius the Deacon or Theodosios Diakonos (Greek: Θεοδόσιος ο Διάκονος) was a Byzantine poet who lived in the 10th century. He is known only through his The Sack of Crete (Greek: Ἅλωσις τῆς Κρήτης, in Latin: De Creta capta), an epic poem in 1039 twelve-syllable lines, written in 962/963 to celebrate the recapture of the island of Crete from the Arabs in 961 by Nikephoros Phokas.
