What is the name of Bilbo Baggins's home?

Bilbo Baggins’s home is called Bag End, a comfortable underground dwelling in Hobbiton, in the Shire. Frodo Baggins later inherits and lives there as well.

Bag End is a luxurious hobbit-hole dug into the Hill above Hobbiton. Unlike the crude image of a dirt burrow, Tolkien describes it as a well-appointed home with rooms, pantries, cellars, furniture, and round windows. Bilbo begins The Hobbit there, leaves for his adventure with the Dwarves, and eventually returns. Frodo’s journey in The Lord of the Rings also begins and ends at Bag End for a time.

The name is a playful reference to a dead-end or cul-de-sac: Bag End is positioned at the end of a lane. Tolkien also borrowed the name from a real house called Bag End, which belonged to his aunt Jane Neave in Worcestershire.

Hobbiton, the Shire, and Rivendell are places rather than the house’s name. Hobbiton is the village, the Shire is the wider region, and Rivendell is the Elven refuge where Bilbo and Frodo travel during their adventures.
