Lucy Pevensie is the first Pevensie child to enter Narnia in C.S. Lewis’s The Lion, the Witch and the Wardrobe.
Lucy discovers the passage through the wardrobe while exploring the spare room of the country house where the four siblings are staying during wartime evacuation. She steps into a snowy wood and meets Mr. Tumnus, a faun who lives in Narnia. Her siblings initially doubt what she has seen.
Lucy’s role is central to the novel because her testimony begins the family’s involvement in Narnian events. She later becomes known for her courage, compassion, and faith in Aslan. Within the series, she appears in several of the Chronicles of Narnia books.
The other Pevensie children eventually enter Narnia as well, but Lucy is the first. Edmund follows her and is tempted by the White Witch’s enchanted Turkish Delight. Peter and Susan enter after the wardrobe’s secret can no longer be dismissed as Lucy’s invention.
