In Greek mythology Stheneboea or Stheneboia (; the "strong cow" or "strong through cattle") was the daughter of Iobates, king in Lycia, and consort of Proetus, joint-king in the Argolid with Acrisius, having his seat at Tiryns; she took a fancy to Bellerophon but was repulsed. As in the Biblical account of Potiphar's wife, she testified falsely against Bellerophon, accusing him of advances and even attempted rape to her husband, who sent him on a deadly mission to Iobates. Bellerophon later returned to Tiryns and punished Stheneboea. Some say that Bellerophon took her for a ride on Pegasus and threw her to the ground but others maintain that this was unworthy of a hero so Bellerophon would not have done such a deed. Others assert that Bellerophon married Stheneboea's sister and consequently it was inevitable that the allegations would be exposed as false so this resulted in Stheneboea's suicide since she feared exposure and public denouncement.
