The Chrysotriklinos (Greek: Χρυσοτρίκλινος, "golden reception hall", cf. triclinium), Latinized as Chrysotriclinus or Chrysotriclinium, was the main reception and ceremonial hall of the Great Palace of Constantinople from its construction, in the late 6th century, until the 10th century. Its appearance is known only through literary descriptions, chiefly the 10th-century De Ceremoniis, a collection of imperial ceremonies, but, as the chief symbol of imperial power, it inspired the construction of Charlemagne's Palatine Chapel in Aachen.
The hall is usually attributed to Emperor Justin II (r. 565–578), with his successor, Tiberius II (r. 578–582) finishing it and carrying out its decoration. However, Byzantine sources present conflicting accounts: the Suda encyclopedia attributes the building to Justin I (r. 518–527), and the Patria of Constantinople to the Emperor Marcian (r. 450–457), although the latter is usually rejected as unreliable. The historian John Zonaras records that Justin II in fact reconstructed an earlier building, which has been suggested as the Heptaconch Hall of Justinian I (r. 527–565).
