Bilbo Baggins lives at Bag End in J.R.R. Tolkien’s The Hobbit.
Bag End is a comfortable hobbit-hole at the end of a lane in Hobbiton, within the Shire. Tolkien describes it as an unusually well-appointed home with round doors, rooms branching from a central passage, and no stairs leading down into a damp cellar. Its name reflects its position at the end of the lane rather than a literal lack of an exit.
The house is inherited by Bilbo from the Baggins family and later becomes associated with Frodo Baggins. It is the setting for the unexpected party at which Gandalf and the dwarves recruit Bilbo for the journey to the Lonely Mountain.
Bag End is sometimes confused with Crickhollow, the house Frodo uses after leaving Hobbiton in The Lord of the Rings. Hobbiton is the surrounding settlement, not the name of Bilbo’s home.
