Lynceus of Samos, brother of the historian Duris of Samos, was a classical Greek author of comedies, letters and humorous anecdotes. He lived in the late 4th and early 3rd centuries BC and was a pupil of Theophrastus. His works, especially his letters and the essay Shopping for Food, show a special interest in gastronomy. He was also the addressee of an important letter by Hippolochus on dining in Macedon. He would be practically unknown if it were not for numerous quotations from his works in the Deipnosophistae of Athenaeus.
