In "The Hobbit", what is the name of the main protagonist?

The main protagonist of 'The Hobbit' is Bilbo Baggins.

Bilbo is a hobbit who begins the story as a comfortable, cautious resident of Bag End in the Shire. The wizard Gandalf recruits him to join Thorin Oakenshield and a company of 13 dwarves on a quest to reclaim the Lonely Mountain and its treasure from the dragon Smaug. Bilbo is initially described as a burglar, despite having little interest in adventure.

During the journey, Bilbo becomes more resourceful and courageous. In the Misty Mountains, he encounters Gollum and obtains a mysterious ring, an event that later connects 'The Hobbit' to 'The Lord of the Rings.' His growth from home-loving uncertainty to dependable adventurer forms the novel's central character arc.

A common mix-up is choosing Frodo Baggins, Bilbo's younger cousin. Frodo is the principal hobbit protagonist of 'The Lord of the Rings,' while Bilbo leads the earlier adventure in 'The Hobbit.' Thorin and Gandalf are important figures, but neither is the novel's central protagonist.
