King Leontes is a fictional character in Shakespeare's play The Winter's Tale. He is the father of Mamillius and husband to Queen Hermione. He becomes obsessed with the belief that his wife has been having an affair with Polixenes, his childhood friend and King of Bohemia. Because of this, he tries to have his friend poisoned, has his wife imprisoned, and orders his infant daughter to be cast out. The daughter, Perdita, survives nonetheless when she is discovered in her basket on the coast of Bohemia by shepherds who adopt and raise her.
