In Irish mythology, Clíodhna (Clídna, Clionadh, Clíodna, Clíona, transliterated to Kleena in English) is a Queen of the Banshees of the Tuatha Dé Danann. Cleena of Carrigcleena is the potent banshee that rules as queen over the sidheog (fairy women of the hills) of South Munster, or Desmond. She is the principal goddess of Ireland.
In some Irish myths, Clíodhna is a goddess of love and beauty. She is said to have three brightly coloured birds who eat apples from an otherworldly tree and whose sweet song heals the sick. She leaves the otherworldly island of Tir Tairngire ("the land of promise") to be with her mortal lover, Ciabhán, but is taken by a wave as she sleeps due to the music played by a minstrel of Manannan mac Lir in Glandore harbour in County Cork: the tide there is known as Tonn Chlíodhna, "Clíodhna's Wave". Whether she drowns or not depends on the version being told, along with many other details of the story.
She had her palace in the heart of a pile of rocks, five miles from Mallow, which is still commonly known by the name of Carrig-Cleena, and numerous legends about her are told among the Munster peasantry.
