Saint Theodore Tiron (Greek: Ἅγιος Θεόδωρος Τήρων) is one of the two recognized saints called Theodore who are venerated as warrior saints and Great Martyrs in the Catholic Churches and Eastern Orthodox Churches. The other saint of the same name is Theodore Stratelates, also known as Theodore of Heraclea, but this second St Theodore may never have had a separate existence. When the epithet is omitted, the reference is usually to St Theodore Tiron.He is also known as Theodore Tyron (Greek: ὁ Τήρων, variously romanized Tyro[n], Tiro[n], Teron). Tīrō is a word from classical Latin meaning a "recently enlisted soldier or recruit". The Latin word was transliterated into Greek with various spellings (Τύρων, Τίρων, Τήρων or Τείρων).
