Chiomara was a Galatian noblewoman and the wife of Orgiagon, chieftain of the Tectosagi, one of three Galatian tribes during the Galatian War with Rome, of 189 BC.
During this war Gnaeus Manlius Vulso was victorious in a campaign against the Galatian Gauls. One of his centurions was put in charge of a group of captives, including Chiomara, described as "a woman of exceptional beauty". He made sexual advances towards her, and when these were rejected, raped her. He then offered, to assuage his shame, to ransom her back to her people, sending one of her slaves, also a captive, with the message. Her countrymen came to the appointed place with the ransom, but while the centurion was counting the gold, Chiomara indicated to them - with a nod, according to Plutarch, or by speaking to them in their own language, according to Livy and Valerius Maximus - that they were to cut off his head. She carried the head home wrapped in the folds of her dress, and threw it at the feet of her husband, saying it was right that only one man alive should have been intimate with her.
The Greek historian Polybius is said to have met her at Sardis, and been impressed with her "good sense and intelligence".
Chiomara is a genus of skippers in the family Hesperiidae.
