Disney's Aladdin franchise features an extensive cast of fictional characters.

The lead character of the series is Aladdin, who was originally a street urchin. During the course of the franchise, he starts living in the palace of Agrabah and becomes engaged to Princess Jasmine.

Abu (vocal effects provided by Frank Welker) is Aladdin's kleptomaniac monkey partner with a high-pitched voice and can talk a little. The animators filmed monkeys at the San Francisco Zoo to study the movements Abu would have. The character is based on the similarly named Abu the thief, played by Sabu Dastagir in the 1940 version of The Thief of Bagdad.

Abu also appears in Kingdom Hearts and Kingdom Hearts II, playing a large role in the latter with his kleptomaniac habits getting him into trouble during Sora's first return visit to Agrabah.

He can also be seen in House of Mouse as one of the many Disney characters that come to watch cartoons. Abu is usually found in the audience, sometimes playing with Iago or dancing along to the musical performances on stage.

In the 2019 film, Abu is featured as a Tufted capuchin.
