In Greek mythology, Pentheus (pron.: // or //; Greek: Πενθεύς) was a king of Thebes. His father was Echion, the wisest of the Spartes. His mother was Agave, the daughter of Cadmus, the founder of Thebes, and the goddess Harmonia. His sister was Epeiros.
Mythological biography 
The story of Pentheus' resistance to Dionysus and his subsequent punishment is presented by Euripides as follows.
Cadmus, the king of Thebes, abdicated due to his old age in favor of his grandson Pentheus. Pentheus soon banned the worship of the god Dionysus, who was the son of his aunt Semele, and did not allow the women of Cadmeia to join in his rites.
An angered Dionysus caused Pentheus' mother Agave and his aunts Ino and Autonoë, along with all the other women of Thebes, to rush to Mount Cithaeron in a Bacchic frenzy. Because of this, Pentheus imprisoned Dionysus, thinking the man simply a follower, but his chains fell off and the jail doors opened for him.
Dionysus lured Pentheus out to spy on the Bacchic rites disguised as a woman, and Pentheus expected to see sexual activities. The daughters of Cadmus saw him in a tree and thought him to be a wild animal. They pulled Pentheus down and tore him limb from limb (as part of a ritual known as the sparagmos). When his true identity was later discovered, officials exiled the women from Thebes. Some say that his own mother was the first to attack him, tearing his arm off and then tearing off his head. She placed the head on a stick and took it back to Thebes, but only realized whose head it was after meeting her father Cadmus.
The name "Pentheus", as Dionysus and Tiresias both point out, means "Man of Sorrows" and derives from πένθος, pénthos, sorrow or grief, especially the grief caused by the death of a loved one. His name appeared to mark him for tragedy. Pentheus was succeeded by his uncle Polydorus.
The story of Pentheus is also discussed by Ovid in his Metamorphoses (3. 511–733). Ovid's version diverges from Euripides' work in several areas. In Ovid's Metamorphoses, King Pentheus is warned by the blind seer Tiresias to welcome Bacchus or else "Your blood [will be] poured out over your mother and her sisters..." Pentheus dismisses Tiresias and ignores his warnings. As Thebes succumbs to the "dementia and the delirium of the new god", Pentheus laments the fall of his kingdom and demands the arrest of Bacchus. His guards instead arrest Acoetes of Maeonia, a sailor who confirms the divinity of Bacchus and tells how the crew of his ship ended up dead after trying to kidnap the young god.
Pentheus, convinced that Acoetes is lying, tries to throw him in jail. But when the guards try to shackle Acoetes, the chains fall off. When Pentheus heard this it caused "something insane behind his eyes [to] tear off its straightjacket." In a rage, Pentheus ran to deal with Bacchus himself. He charged through the woods straight into a bacchanalia. Driven to a frenzy the participants thought Pentheus was a boar and attacked him. His mother was the first one to spear him and then the group tore his flesh apart with their bare hands.
Finally, all acknowledged Bacchus as a god.
