Baloo is the deuteragonist of Disney's 1967 animated feature film The Jungle Book. He's a fun-loving, easygoing, loyal, and good-natured sloth bear who becomes best friends with a “man-cub" named Mowgli.

In the original book by Rudyard Kipling, Baloo was very different from his Disney incarnation. In the book, Baloo was a humorless, serious, and strict aging sloth bear who utilized militant discipline while mentoring Mowgli and the wolf cubs. When Walt Disney began to develop a film based on the novel, Bill Peet originally wrote a version that was set to be darker and slightly closer to the source material, but many changes were made, including Baloo's personality, which was changed into a fun-loving, humble personality. While that version of the film was scraped, the final version still utilized many of the characterizations featured in Bill Peet's version including Baloo's, with his relationship with Mowgli serving as the heart of the film.

Baloo's trademark song, "The Bare Necessities", was actually written for Bill Peet's original draft of the film. When Walt overtook the project, "The Bare Necessities" and the accompanying songs were cut, with the Sherman Brothers being brought on to write the new songs. However, the filmmakers loved "The Bare Necessities" and pleaded to have it remain in the film; Walt would eventually agree.
