Duris of Samos (or Douris) (Ancient Greek: Δοῦρις ὁ Σάμιος; c. 350 BC – after 281 BC) was a Greek historian and was at some period tyrant of Samos. Duris was the author of a narrative history of events in Greece and especially Macedonia from 371 BC to 281 BC, which has been lost. Other works included a life of Agathocles of Syracuse and a number of treatises on literary and artistic subjects.
