Goetia (from the Greek, sorcery) most commonly refers to the Lemegeton, or Lesser Key of Solomon (Lemegeton Clavicula Salomonis), an anonymous seventeenth century manual on demon invocation popular with eighteenth century occultists, most notably Aleister Crowley and AE Waite.

The book, cobbled together from a variety of medieval and Renaissance sources, purports to be the magical manual of the biblical King Solomon, whose legend has long included tales of servant demons conjured by the king to do his bidding.

The book is divided into five parts: the Ars Goetia (Art of Goetia), the Ars Theurgia Goetia, (art of theurgic goetia) the Ars Paulina (Art of Paul the apostle), Ars Almadel (Art of the talisman; an almadel is a magical diagram of the cosmos), and Ars Notoria (The notary art; a previously existing work).
