The Phooka (Ol Irish), (also Pooka, Puka, Phouka, Púka, Pwca in Welsh, Bucca in Cornish, pouque in Dgèrnésiais, also Glashtyn, Gruagach) is a creature of Celtic folklore, notably in Ireland and Wales. It is one of the myriad of fairy (faery) folk, and, like many faery folk, is both respected and feared by those who believe in it.
