For the geometer moth genus, see Dirce (moth)

Dirce (; , , modern Greek , meaning "double" or "cleft") was the wife of Lycus in Greek mythology, and aunt to Antiope whom Zeus impregnated. Antiope fled in shame to King Epopeus of Sicyon, but was brought back by Lycus through force, giving birth to the twins Amphion and Zethus on the way. Dirce hated Antiope and treated her cruelly after Lycus gave Antiope to her; until Antiope, in time, escaped.
