Theophano Martiniake was a 9th-century Byzantine empress and the first wife of Emperor Leo VI. Born in Constantinople to the noble Martinakios family, she was linked to the Amorian dynasty through her ancestry. Following her marriage to Leo, which was arranged by Basil I, she eventually withdrew from the imperial court to live in a monastery in the Blachernae suburb. She is remembered for her religious devotion and her status as a saint within the Eastern Orthodox tradition.
