Histiaeus (, died 493 BC), the son of Lysagoras, was a Greek ruler of Miletus in the late 6th century BC. Histiaeus was tyrant of Miletus under Darius I, king of Persia, who had subjugated Miletus and the other Ionian states in Asia Minor, and who generally appointed Greeks as tyrants to rule the Greek cities of Ionia in his territory.

==Scythian campaign of Darius I (circa 513 BC)== thumb|upright=1.2|The Greeks under Histiaeus preserve the bridge of Darius I across the Danube river. 19th century illustration. According to Herodotus, Histiaeus, along with the other Chiefs/Tyrants under Darius' rule, took part in the Persian expedition against the Scythians, and was put in charge of defending the bridge that Darius' troops had placed across the Danube River. The Scythians attempted to persuade Histiaeus and the others to abandon the bridge; one faction, led by Miltiades of Athens, at that time tyrant of the Chersonese, wanted to follow the Scythians' advice. However, Histiaeus argued that they should stay, as they owed their positions as tyrants to Darius and would surely be overthrown if he were killed.
