In C. S. Lewis's fantasy novels the "Chronicles of Narnia", The Kingdom of Archenland is a nation to the south of the Kingdom of Narnia, and to the north of both nations' occasional (and final) enemy, the Calormen Empire.

The Lady of the Green Kirtle, also called Queen of Underland and Queen of the Deep Realm, is the main antagonist in "The Silver Chair" by C. S. Lewis.
 She is sometimes called briefly the "Green Lady" (on analogy with Jadis, the "White Lady"), and she is known also as the "Emerald Witch"; neither name, however, appears in Lewis's text.

 She is foiled by three friends of Aslan: Eustace Scrubb, Jill Pole, and Puddleglum.
