The Belevi Mausoleum, also known as the Mausoleum at Belevi is a Hellenistic monument tomb located in Turkey. The intended occupant of the tomb may have been Antigonus Monophthalmus (r. 323-301) or Lysimachus (r. 323-281), and it may subsequently have been the burial place of the Seleucid king Antiochus II Theos (r. 261–246 BC).
