In Greek mythology Stheneboea or Stheneboia (the "strong cow" or "strong through cattle") was the aughter 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 myth 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.
