Bilbo Baggins is the fictional character associated with the poem beginning “Not all those who wander are lost.”
The lines appear in “The Riddle of Strider,” a poem included in The Fellowship of the Ring. The poem describes Aragorn, who is introduced under the name Strider, and was written by Bilbo. The complete line is “Not all those who wander are lost,” followed by imagery about old strength, deep roots, and a crown.
The quotation is often treated as a general inspirational saying and is sometimes attributed directly to Tolkien. Within the story, however, it is part of Bilbo’s poem about Aragorn. The passage helps signal that Strider is more than a wandering ranger and hints at his royal identity and destiny.
