John VII Palaiologos or Palaeologus (Greek: Ἰωάννης Παλαιολόγος, romanized: Iōánnēs Palaiológos; 1370 – 22 September 1408) was Byzantine emperor for five months in 1390, from 14 April to 17 September. A handful of sources suggest that John VII sometimes used the name Andronikos (Ἀνδρόνικος), possibly to honour the memory of his father, Andronikos IV Palaiologos, though he reigned under his birth name.
